20,000 sets were produced with 5,000 sets having the #1 card autographed. Only the #1 card was issued with an autograph. The sets that had the #1 card autographed have blue printed backs while those sets without the #1 card autographed are printed in red.
There are 3 entried for this set - http://www.tradingcarddb.com/Subsets.cfm/sid/129078 / http://www.tradingcarddb.com/ViewSet.cfm/sid/129077/1982-ASA-The-Life-of-Mickey-Mantle- / http://www.tradingcarddb.com/Subsets.cfm/sid/129079 . The notes are mostly wrong in all three.
There should be two entries only - Red and Blue backs. As far as I know, they are not SN though the print run is known. Not sure where the person who entered the three sets here got their information. The picture that is entered on all three set entries are not autographed so should only be in the red set.
This is an example of where a note field in the "Overview" would be useful putting the print run info and the difference between the two variations of the set instead of trying to put a Note to each card.
