Happy #HumpDay. A bit of a mystery, this button has an Egyptian motif and is marked "Made in USA." We don't know much about it except that it's made of celluloid, the world’s first commercially successful plastic. Celluloid was invented by John Wesley Hyatt in 1869. It was a nice substitute for ivory.
