The two most interesting chips are the yellow Tango and the pink chip with a picture of a building.

The yellow Tango (different color from typical gold Tango) with white ring has a four leaf clover inlaid on the reverse. Interestingly it is a three leaf clover with a fourth leaf added to appear to be a four leaf clover. Chip was custom made by USPC probably for a deep pockets gambler.

Pink (or ROSE) colored chip with the building was ordered by the CEO of USPC, Clifford E. Albert. The chip was ordered in 1915 for presentation at his Alumni Dinner held in Cincinnati. The building is a picture of his alma mater, the Rose Polytechnic Institute. I assume that is why the chip is rose colored.

I'll try and also bring this case to the show.

The reverse of both chips is shown below.
