A nice find from a thrift store. I bought it for $1 and it is currently valued over $150.
This brooch is an early Coro Signed Book Piece. The brooch would have been created between 1920 and 1940, during the Art Deco period.
The vintage pieces is large measuring 3.25" in length. It is done in hand enameling with clear rhinestone petal edging and has a moving stamen tipped in blue rhinestones.
