Vintage & Archival

Authentication Changes With Era

Vintage pieces often predate current labels, codes and digital identifiers. Use period-appropriate evidence rather than comparing every older item to today’s boutique product.

How to Use the Library

Authentication Works Best as a Process

01

Identify the exact item

Start with designer, category, product family, likely era, material and complete style reference.

02

Compare independent evidence

Check labels and codes alongside construction, materials, hardware, dimensions and documented context.

03

Resolve contradictions

A correct-looking number cannot override a mismatched model, transplanted label or inconsistent construction.
