Silver Bamboo Stick Pin - Antique

Look at the old clasp - You insert the pin and then push up the lever to hold in place! Marked Silver. This pin has provenance. I purchased at an estate auction of the listed artist Virgil Cantini. This was in his personal box of trinkets. Virgil was an important metal smith and enamelist. He founded the Fine Arts Department at the University of Pittsburgh. A bit over 3".
