Rare, large vintage sterling silver William Spratling butterfly brooch. Circa 1940's. This one is a whopper! Measuring about 2 3/4 inches wide x 2 1/4 top to bottom. Very recognizable and often used to inspire similar pieces by other masters. Nice three-dimensional effect with the overlapping wings. Marked with Spratling Silver oval and round primary marks on reverse, eagle assay 1. Overall good condition with minor age wear.
There is a good repair reconnecting one end of the clasp as shown in the picture. Works perfectly. The reverse retains an original, almost black patina, while the front has been polished retaining patina in the creases.
