Look for these when you get to the convention, unfortunately I can't go...

Slot cards aren't the only "plastic" cards available for the collector...

Today's Slot Card City College are TC or Table Cards (as described in Lamb and Wells catalog). These were used in the Pit to track table play.

The laminated paper was obtained just before the Horseshoe was bought out by Harrahs. I got the Sahara within the last year. The plastic Orleans and San Remo are older.
