To promote their having special Baseball Cards with their Cereal in 1962 which included 1 panel that contained 2 of the Cards

On one side was  card No 5 Mickey Mantle  and on the other side was card No 6 Roger Maris 

Often these were removed from the magazine and cut apart with each card having the Post Ad on the back side

This auction is for an insert which is still intact and the Life Magazine suscription Order Card which was attached to the cards and held them in place in the magazine. Unfortunatly, this has been detached from the cards but it is here. 

These cards appear to be in really nice condition no tears  no creases . There is some minor toning from age

I am no card expert  but you are   so please look the photos carefully and bid accordingly   This is the only set I have and once the auction is over they will be sold and gone
