6 Vintage Guy Buffett Coasters French Waiters "Bottle Brigade" Excellent Cond!

Set of 6 (SIX) square cork-backed drink coasters featuring artwork by Guy Buffet ("Change of the Bottle Brigade"). They are in excellent, gently-used condition with no dents, tears, or other obvious signs of wear or damage. Each measures 4 inches square. I no longer have the original box they came in but believe they came from Williams-Sonoma.
