A practical, curator-minded glossary for ocean liner history and responsible collecting. Definitions here favor use (how terms are applied in real listings, archives, and museums), not internet folklore.
In collecting, attribution ranges from modest and well-supported (“White Star Line, fleet pattern, c. 1910–1920”) to highly specific claims (“Titanic, 1912”) that require much stronger documentation. A responsible attribution states what is known, what is inferred, and what remains unknown.

“Authentic” should mean more than “old-looking.” It refers to whether the object is what the claim says it is—ideally supported by maker’s marks, construction details, period materials, or documentation. A correct label might be: “period souvenir,” “company-issued,” “shipboard use,” or “reproduction,” depending on evidence.
See also: Reproduction, Period piece.
Badges can be shipboard (crew/uniform context), company (corporate identity), or purely commemorative/souvenir. Without documentation, a badge rarely proves ship-specific use on its own; it more reliably indicates a line, route, organization, or occasion.
See also: Souvenir, Provenance.
Builder’s plates are iconic but can be complicated: some are original removals, others are later castings, replicas, or commemorative pieces. Material, casting quality, mounting traces, and chain-of-custody matter.
See also: Reproduction, Chain of custody.
A strong chain of custody reduces guesswork. It may include crew letters, invoices, estate documentation, museum deaccession records, or dated photographs showing the exact object. “Grandpa brought it back” is a lead, not a chain.
See also: Provenance, Documentation.
Company-issued items often have consistent patterns, supplier relationships, and marking conventions. This category is different from “period souvenir,” which can be contemporary yet not official.
See also: Fleet pattern, Souvenir.
Deaccession records can be excellent evidence: they can verify identity, acquisition context, and prior catalog notes. However, even museum records can contain older assumptions—treat them as strong, but not infallible.
See also: Documentation, Attribution.
Documentation is strongest when it identifies the specific object (not just “something like this”) and is dated/traceable. A single undated note is weaker than a consistent set of independent records.
See also: Evidence, Chain of custody.
Ephemera is often the clearest window into shipboard life and company branding, and it can be dated precisely by sailing, port, event, typography, and printing style. It can also be reproduced—so printing method and paper matter.
See also: Period piece, Reproduction.
Evidence can be physical (marks, construction, wear, materials), documentary (dated records), or comparative (matched to verified reference examples). “It looks right” is a starting point, not a conclusion.
See also: What Counts as Evidence?, Attribution.
Fleet patterns explain why many objects cannot be reliably assigned to a single ship: the same china, silver, linens, or printed forms may appear across multiple vessels, sometimes across decades, and often through refits or supply changes.
See also: Ship-specific attribution, Pattern variant.
“Fantasy” does not always mean intentional fraud—sometimes it’s enthusiasm, assumption, or copied lore. The curator approach is to separate the object from the narrative and evaluate claims against evidence.
See also: Red flag, Attribution.
Many gallery trays are hotelware or institutional supply pieces. A crest or line mark can indicate company use, but ship attribution depends on markings, documentation, and verified comparatives.
Hallmarks can verify material and sometimes maker/date, but they rarely verify a ship. A sterling hallmark means sterling; it does not mean “Titanic.” Use hallmarks to identify what the object is, then build attribution cautiously.
See also: Maker’s mark, Hotelware.
Hotelware can be “right” for a line and still be hard to assign to a ship, because suppliers served multiple clients and designs were repeated. Understanding hotelware conventions helps avoid over-attribution.
See also: Fleet pattern, Attribution.
Property marks can be strong for identifying a company or institution, but still may not identify a particular ship. They are often applied consistently across many objects and can be added later in the supply chain.
See also: Company-issued, Maker’s mark.
Not every object can be placed on a ship. “Unknown” is not failure; it is a responsible conclusion when the evidence ceiling has been reached. This site treats uncertainty as a normal, visible part of collecting.

“Ocean liner” is not a synonym for “big ship.” Liners were built to keep schedule across open seas, prioritizing seakeeping, strength, and endurance. Cruises are defined by leisure; liners are defined by transport.

Lots can hide gems—or mix unrelated items that create accidental “provenance by proximity.” Treat each object on its own merits, then consider whether the lot context adds credible support.
See also: Provenance, Fantasy listing.
Maker’s marks are excellent for identifying what something is and where/when it could have been made. They are often misread as a “ship mark.” Use them as a foundation, then evaluate company/line context separately.
See also: Hallmark, Property mark.
Ocean liner material culture includes everything from ephemera and uniforms to fixtures and fittings. Objects are interpreted as parts of systems—supply, service, branding, class structure—not as isolated trophies.
See also: Collecting guide.
Narratives can be valuable leads, but they are not evidence unless they can be checked. The curator approach is to separate the story into testable claims, then evaluate those claims against marks, dates, and documentation.
See also: Evidence, Documentation.
Original finish can carry clues: how an object was held, used, washed, mounted, or stored. Heavy polishing or restoration may remove evidence (especially on metals) even when it improves appearance.
See also: Period piece, Evidence.
A 1910s souvenir postcard can be a period piece without being “official.” Likewise, an Edwardian teaspoon can be period-correct without any shipping-line connection. “Period” is about date—not proof of ship service.
See also: Company-issued, Souvenir.
Provenance is strongest when it identifies the exact object and provides a chain of custody. Many listings use “provenance” to mean “a story,” “a family claim,” or “it came from an estate.” Those can be leads, but they are not the same as documentation.
See also: Common Problems With Provenance, Chain of custody.
Variants matter because small differences can indicate different contracts, refit eras, or supplier changes. A near-match is not automatically a match; record what differs and look for verified comparatives.
See also: Fleet pattern, Reference example.
Examples include: vague phrases (“from an old sea captain”), no photos of marks, implausible certainty (“one of a kind Titanic”), copied listing text, or a mismatch between material/date and the claimed ship. Red flags prompt verification—not automatic rejection.
See also: Fantasy listing, Evidence.
Reference examples are the backbone of responsible identification. A single match image online is weaker than multiple independent verified matches with consistent marks, dimensions, and date context.
See also: Comparative method.
Reproductions can be collectible on their own, but they must be labeled accurately. Look for modern manufacturing cues, incorrect marks, artificially aged surfaces, and “too perfect” condition relative to alleged use.
See also: Authentic, Original finish.
This is how most object identification works when paperwork is missing. The method succeeds when comparisons are precise and verified—not when they rely on “similar vibe” images.
See also: Reference example, Evidence.
This is a high bar. Many lines used fleet patterns, and objects circulated through refits, transfers, and disposals. A ship-specific attribution usually requires documentation or an unmistakable ship name/identifier applied in a verifiable period.
See also: Fleet pattern, Documentation.
Souvenirs can be period-correct and historically valuable, but they are often mistaken for “shipboard used” artifacts. The key question is whether the object was issued for use (service) or sold as a keepsake (retail).
See also: Company-issued, Period piece.
Crew items often have stronger personal provenance (letters, service records, family history) but still require caution: a crew member’s possession does not always prove shipboard use of the exact object.
See also: Chain of custody, Documentation.
The timetable is more than a marketing detail; it shapes design and operation. Ships intended to hold schedule across open ocean routes required endurance, redundancy, and reliability that differed from pleasure cruising.

Branding can help identify a line or era, but many motifs are generic nautical design. Treat visual resemblance as a clue, then verify with marks and comparatives.
See also: Property mark, Comparative method.
Wear can support authenticity, but it can also be simulated. The goal is not “more wear = more real,” but “wear that makes sense for the object’s materials, construction, and claimed use.”
