1.5" tall by 1-15/16" across, this stiff sheet of celluloid has its front featuring photos in black against a simulated mother-of-pearl bkg. The reverse of the piece is pale blue. There is no collet but rather a pair of celluloid circles which anchor the bar pin and catch. The only previous example we can find is from an Anderson auction in 1992. He called it "first one known in the field" and it exceeded $2,500. Here's what we think is the second known in the field in essentially Mint as made condition.
