Vintage Antique Silver Art Deco 1930's Abalone 2024 Shell Inlay Question Mark Stick Pin Hat Pin Brooch Fashion Accessory Jewelry

An unusual antique silver stick pin with a question mark design and inlaid with iridescent abalone shell. I believe it is from the Art Deco era and 2024 was likely made sometime in the 1930's.

It measures .5" across and just shy of 2.5" long.
