Rhodium plated unfoiled open backed faux-flawed emerald belly with small round faux-ruby eyes mouse brooch with security clasp. Marked "NAPIER ©" on the back. Measures: 1 5/8 inches long by 1 1/16 inches wide. Condition: Very good; it's missing one whisker, but it's hard to tell unless looking closely. The other brooches from this collection were featured in a 1965 advertisement.
