For sale here is a BIG and RARE vintage 1920s 30s Art Deco geometric machine age handmade multicolor celluloid disks on a black Bakelite bar brooch pin. This is an early example of the classic Bakelite Disks on a Bar design brooch. The Bakelite version is all Bakelite. In this example the maker still used celluloid for the disks but placed them in a row on a black Bakelite bar. It's the only one of this version that I've seen in my over 40 years of collecting vintage plastics! Guaranteed genuine vintage 1920s 30s celluloid and Bakelite original pin, not a reproduction or re-make from old parts. Measures 3-1/8" long by 1" wide. Excellent vintage condition with just fine light wear as shown - please view the photos, read the description, and ask all questions prior to purchase. I am open to reasonable offers from serious buyers.
