Mexican Sterling Donkey Brooch 925

Calling all Democrats! This adorable sterling with abalone accents figural donkey brooch hails from Mexico. Signed with the initials RRB, the brooch is in excellent vintage condition. We have seen this same artist's work with the early eagle insignia but it is not found on this piece so we feel it is a piece from the early 40's. The hand etched face is sweetly done with an abalone accent over the eye giving this 2 1/8" x 1 1/2" guy such character. Marked on the back Sterling Mexico 925 and the designer's initials, this sterling piece weighs 7 grams.
