Printed in Italy between 1964 and 1964, this is the first time Pele was featured in a set by Panini.  Founded in 1961, Panini would quickly rise to the top of trading card manufacturers, making them the most widely known name in the industry today.  This particular set featured 421 stickers and were designed to be affixed into an album.  The sticker was issued with three different back variations, with the Valida back being the most difficult to locate.
