A most unusual pin with 21 tiny blue painted shells glued to a clear lucite base that is shaped to form the stems of a bouquet. On the back is glued a single metal pin shaft to attach the piece to clothing. There is no clasp or safety catch. This piece has been in my family for many years and I can be almost certain it was purchased in Florida in the 1930s or 1940s where a family member vacationed every summer and brought back souvenir gifts. Most likely hand made and purchased from a street vendor.
It is in good condition for its age, but probably too fragile to be worn on a regular basis. Photos of the back show that the shells are glued in groups to round lucite pieces. There are letters on the pin back (now brown with age) and all that can be read is "Pat" (presumably an abbreviation for patented). Measures 4-1/2 inches tall x 2-1/2 wide. A prize for the collector of early plastic jewelry.
