NOS or Not: What Provenance Really Proves

A vintage deck is a claim about the past, and provenance is the evidence for that claim. When a seller tells you a board hung in one garage since 1988, the interesting question is: what would make that story checkable?

The strong signals

Dated purchase receipts, period photographs showing the actual deck, shop inventory tags, and continuous-ownership statements are the gold standard. On the deck itself: oxidation patterns that match the claimed storage, consistent yellowing of white underlays, and hardware shadows that agree with the mounting history.

The weak signals

A shrink-wrapped deck is not automatically NOS — re-shrinking is a cottage industry. A famous name in the story is not evidence; a signature without a witness or a photo adds sentiment, not certainty. Madera's authenticators treat every unverifiable claim as absent, and our listings only state what survived scrutiny.

When you sell through Madera, send whatever paper you have with the deck. Provenance that passes review is summarized on the listing and travels with the board to its next owner.
