The on-line Chip and Token Historical Report has nothing earlier than 1984 entries in it. I searched the historical report for Shy Clown and got nothing so that doesn't help with the roulette chip color as the manufacturer named it. I believe Shy Clown was open 1976-81.

I wonder if anyone has a file of paper copies of the monthly reports before they started putting them on the Web. That is the kind of thing that the Club should have on file if there really were earlier reports. I think Howdy was the Historian in the early years so he might have something.
