Sold by several accessory companies and through his own firm, Katz elaborated the same allegoric motif on a series of badges of great fineness and amazing formats.
You could fine this piece as a concealed ID plate, where the badge shown would spin around one edge to reveal the owner’s information at the back.
Unsigned piece. Diameter 40mm.
