For sale here is a HUGE and very rare Art Deco vintage 1930s geometric design Bakelite brooch pin in transparent marbled apple-juice Bakelite with carved and overdyed decoration in black and red. This design is pictured in the original Bakelite Jewelry book by Davidov and Dawes in the Art Deco geometric Bakelite section near the beginning of the book. Guaranteed an authentic vintage 1930s 40s Bakelite brooch, and not a reproduction or re-make from old parts. Original inset pin mechanism as expected from this era. Measures 3-5/8" long by 7/8" 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.
