Sticker

In autograph cards, a sticker auto refers to a signature applied to a sticker that is then affixed to the card, rather than signed directly on-card. Sticker autos are generally less valuable than on-card autographs because the signature feels less personal. However, sticker autos allow manufacturers to include more players in their autograph checklists. In the broader hobby, 'sticker' also refers to collectible sticker albums like Panini World Cup stickers.
