KEM, Copag, Bicycle, Da Vinci, Trump. I played Crazy Eights with Bicycle's going back to my first decade. I've played poker with Copag cards at a home game in Camp Hill, PA. In Atlantic City @ the Trump Taj Mahal on the crisp, green felt I fingered some Trump brand playing cards. Tried my hand at human anatomy and bought some sturdy Da Vinci cards. But my favorite kind of card, other than a Topps Unitas or a Fleer Jordan, is a KEM Cellulose Acetate.
