A Coro butterfly pin that looks to be an early one. The Coro mark is in script and has an r that matches the one in their 1920s mark, although similar pieces were manufactured in mid 1940s. Made of thin stamped brass, it has a single red prongset navette for the body and clear rhinestone for the eye. One clear rhinestone is missing, which I will be happy to replace if desired. The pin measures 1 1/2" wide and 1 1/4" high. Very good condition with a small bit of wear near the center left of the red rhinestone.
