Once in a blue moon a collector comes across something that almost no one has ever seen. That's exactly the case with this small group of cards.
I purchased these when they were still attached to a little-known Venezuelan album called El Mundo del Beisbol. There just doesn't seem to be any information about it anywhere.
SGC has graded each of these a 1, and I believe the assessment is accurate for each. It seems unlikely that the hobby will see any more of these for a long time to come. Included are George Brett, Reggie Jackson, Carl Yastrzemski, Frank Robinson, Joe Morgan and Ron Guidry.
Here's the link to the listings:
