Display your membership in the Night Owl Book Club! The only requirement for joining is that you stay up late reading. I have this cool book The Graphic Art of the Enamel Badge by Ken Sequin. It's a history of enamel pins from 70+ years ago. They were mostly made for clubs and associations, and I thought it would be cool to invent my own bookish club.
3/4 inch (2 cm) soft enamel pin in silver-colored metal with dark blue enamel. Black rubber clasp.
