Move over trapezoids! If I had to choose a favorite shape, I'd settle on the not-so-widely known trefoil design. This trefoil button from the 1920's or early 30's makes my heart spin. Erupting in a 2-tone style, the Bakelite alternates between licorice and creamed corn—topped with a nifty little Bakelite bead. It's a sizable and electrifying button, definitely what I'd call a dramatic zinger.
