Linda Layden Scrimshaw Schnauzer 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 Schnauzer 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 1/2" long with the keychain  . Weight is 11 grams.
