I did not study this in depth, but pretty certain that what is being noticed is caused by Maris cards coming from different cereal box panels. Maris was like on 5 different panels on various cereal in 1962 (plus the Life magazine card). As such one can find all these variations, although some are tougher than other depending on each cereal's particular sales. As one might assume, this concept is applicable to all players though-out the set as well as really every Post Cereal issue. In fact that is what Post Cereal Master Set collectors attempt in putting there sets together -- one card of each player from every different cereal panel the player appeared on (plus in the case of the 1962s, the Cash, Adcock, and Cepeda variations occurring on the same cereal box panels where the company attempted to correct an error during the promotion). One can tell these variations thru not only color, but picture cropping differences, packaging adhesive on the back, and/or occasionally differences in the narrative portion of the card. Dan Mabey has produced books which are still available on the various Post Cereal Baseball promotions with a good level of detail in each about this situation. The books are an invaluable tool for anyone attempting to put together a master set. (Good luck with the 62 set as that one has over 500 cards in it!)
