My computer has not been able to upload to the board for sometime. I will try to see if I have one of the chips with the design in the house (I keep my Cuban collection in a vault) and email it to you and you can post it.

The design is simple, a large "C" in the correct direction and another identical "C" overlpaping and looking the other way. In the center, where they both meet, is not exactly diagonal but rather looks like the front of the chip shown here. If you made a note, I mentioned then that I would ask you to make me a scan at some point in order to use it on the Cuban catalog as the origin of crossed C casino.
