My advice to anyone who decides to collect Bakelite buttons is that if you ever see a cookie button with a triangle on it...TAKE IT AND RUN! In my experience, these are the absolute hardest cookies to find. True Bakelite rarities, I have no idea why they're so scarce. These three triangles in black, red and butterscotch are set at the base ofcreamed corn hollows. I'd love to add a fourth one to my set, but until then I'll just be thankful and count these as pennies from heaven.
