Signed FRANCOIS Coro Brooch White Black Aster 4" Rhinestone Center 1940 Rare Vtg

Vintage, Rare and very hard to find signed brooch.1940 original Francois signed Enamel Brooch Pin 
Enamel has some wear from age, edges have a few areas where enamel has worn off on petal edges and stem and sill looks beautiful. Back of brooch has some missing enamel as shown in photos. Nothing that wouldn't be expected from the age of this brooch. 
A great collectors piece
