Practical Application Example
A Tokyo-based reseller recently identified a presumed 1992 Louis Vuitton Keepall as actually being from the rare 1987 Aviation collection. The YesSheet system detected:
- 8-pointed star rivet pattern only used for 2 years
- Matte brass finish inconsistent with 1990s production
- Specific heat stamp font variant
Subsequent auction records verification confirmed this identification boosted the bag's value by 320%.
