This gold plated brooch was made by the Metropolitan of Modern Art, which regularly reproduces their vintage items from the 18th, 19th and early 20th Century. The original ram could have been in the 1920-1940, but this one must be called Art Deco style. This ram is 2 3/8" tall and 2 1/4" wide and has a sturdy safety clasp. Marked MMA on the lower back. Excellent vintage condition. Chinese New Year is February 19.
