JMF & Co Sterling Silver Charm - Holy Bible with Lords Prayer

Dating to the 1950s/1960s or so and manufactured by JMF & Co, here's a Sterling Silver (hallmarked on the inside spine as pictured) book locket charm in the shape of the Holy Bible. Open the charm to reveal The Lords Prayer (under plastic) in its entirety. Size, when closed, is 9/16" high (without ring and bale) x 7/16" wide. Weight is 2 grams. Opens easily, closes securely. Condition is wonderful with a mellow patina to the silver.
