Here's a jet-black button that must've been fun to design. The eye-shaped middle section dips inwards as if custom-made for gliding one's thumb into the sculpted basin. Inside the eye are 13 chiseled spots that remind me of smaller eyes—all peeping out of the larger eyeball. The carved lines traveling to the edge of this button are possibly eyelashes. Tested as Bakelite, circa 1935.
