Linda Layden Scrimshaw Boxer Dog Keychain with Sterling Silver Charm

This piece is vintage old store stock. I think that it was intended to be a pendant, but I added the keychain. The scrimshaw boxer dog was hand drawn by scrimshaw artist Linda Layden on plastic. The charm is sterling silver. It is not marked, but I did acid test it. Frame that holds the scrimshaw is pewter. artwork and frame is 1 1/4" in diameter. 3" long without the keychain  4 " long. Weight is 12 grams.
