A vintage trembler insect pin that reminds me of the Hattie Carnegie pins, but this one is unmarked. Rhinestones cover the head and part of the wings, with blue rhinestone eyes in the front.
The wings are attached with tiny springs and 'tremble' whenever there is motion. This piece is in excellent condition and very collectible.
It's 1 3/8 inches long and the best kind of little critter to have crawling up your lapel.
