The Method applied to 20th-century furniture
The method interrogates 20th-century furniture the same way it interrogates Murano glass or livres d'artiste: counterfeit pressure scales with value and fame; coherence between claimed age and physical evidence is non-negotiable; timing matters more than beauty. You receive a risk tier, the exact verification checklist, and the Discipline Ceiling — the maximum you can pay without losing, not what the piece is worth.
The Method's take
Apply the patina law: real wear is hierarchical (uneven, where hands and feet touched; coherent with the piece's claimed life story — sea air = aggressive; sun = differential; smoker's home = dirty film). Fake aging is democratic: uniform, exaggerated everywhere, theatrical. Hardware, joints, and veneers must date with the structure — replaced parts are acceptable if declared and priced; concealed ones are alarm signals. Above your affordable-loss ceiling, a written opinion from a recognized expert comes before purchase — the market pays certification, not your correctness. For manufacturing details specific to a designer or workshop, verify with a category expert before deciding.
The math
A mis-attributed chair bought for €8,000 that auctions unsold and trades privately at €1,200 costs you €6,800 plus years of locked capital and reputational noise. A heavily-restored piece bought as original and later rejected at consignment costs the purchase price, storage, failed sales commissions, and the psychological tax of a burned eye. The 24-hour pass is €100; the annual pass €3,800. One avoided mistake pays for decades of access.
