Celluloid is one of the earliest forms of plastic. It became very popular after the first World War due to metal shortages. Pieces like this were incredibly popular in the 1930s/1940s. This pin actually has room for a tiny flower in it! I’m happy to include the faux yellow flower with your purchase! Such a beautiful little treasure!!!
