Black leather fob is 1.75” in dia. It holds a 1.25” real photo celluloid fastened to the leather by means of a round brass stud visible on the leather reverse. Where the strap goes through the loop, there is a very fine crack in the leather surface but leather remains very intact and not in danger of coming apart. The celluloid button itself is essentially Mint. Rare. From the Morry Greener Collection.
