This fabulous pin has two "trembling" flowers that vibrate in such a marvelous way. The petals are black, purple and white, and the centers are sparkling topaz rhinestones. The pin measures 3-1/4 x 1-7/8 inches, and does have some minor wear on the enamel, but not enough to detract from the beauty of the pin. It is marked on the back "WEISS" (no copyright symbol, and I believe this pin is older than 1955). I'm certain this must be a book piece, but I haven't found the right book yet!
