This is one of the cards in our collection that is so rare that no authentication companies are currently able to make a determination as to its authenticity.  Believed to have been printed in Mexico by Larin Chocolates, this set can be dated to 1959 by the text that appears on the reverse of the Garrincha card referring to his success in "last year's World Cup held in Sweden."  We have only seen the Pele and Garrincha cards from this set, but based on the card numbers there are at least 45 cards included in the publication.  The cards themselves are printed on very thin stock, contain biographical information on the reverse, and feature low resolution black and white photos on the front.  Any information about this set would be greatly appreciated as it could assist PSA in being able to properly identify and grade this issue.
