This is actually a known error.
I believe the error is actually the front. I don't think the yaz #152 exists in the '68 Venezuelan set as its own card, only as the error. Don't quote me though!
Edit: I'm wrong the card #152 of Carl with the correct back is a thing. Seems to actually be rarer than the error which is interesting.
Also, Nice first post!
