The blog describes the Gorey/NYCB pendant as a rarity: "According to Gorey bibliographer Edward Bradford, the following button was also available with a chain so it could be worn as a pendant necklace."
The pendant is a vintage original, not a reproduction, in excellent condition.
Button is 2 1/4" in diameter; chain is 23" long
