Once upon a time there was a chip listed in ChipGuide with this exact monogram as being from Cuba, and I had posted this chip showing it was from Uruguay, for certain which...

...though, does not discount the original ChipGuide entry was not correct since we known for a fact that chips did travel from Europe to Cuba (...and we stopped there).

Recently, I bought this bone chip with the same monogram which we know is from Uruguay as well and, now, as of this morning; I have very strong reason to believe it may have been an influence in attributing the one chip that was previously listed as being from Cuba but, where, I do not recall. Thus my question; is there a record of that listing or an image of the chip?

Previously, when I introduced this chip I noted the unusual burned-in cancellation and described what I read as saying; "You can only call me as being a 1-unit chip without any original origin or monetary unit."

Any help regarding the original listing, further confirmation of the monogrammed chip being used in Cuba or consideration is appreciated.
