I am not convinced that what is spelled out is actually "Copa Cabana". Look at all 3 of the letter a's. They are identical. But the 2 letter c's are both different. This is consistent with the imaged jetons from Spike and the plaques. Also, is the "p" in "Copa" really the letter p, or might it be the letter r?

I still do not know what it would spell, but there is a chance here that it does not spell out "Copa".
