"Yves Saint Laurent Rive Gauche / Brooch"
Quite rare brooch in gilded metal and colored resin in imitation of a cameo signed Yves Saint Laurent Rive Gauche. This signature seems to be a marking quite early in the production of the couturier and his "couture" jewelry. This brooch does not seem to have been used or used little.
