You are looking at a strip of Near Mint Condition Batman: Catwoman Defiant and Penguin Triumphant Promo Stickers by DC Comics from 1992. These stickers were produced to generate interest in the 2 Batman prestige format comics listed above. I have also listed the promo bookmarks separately for the comics as well.
They will ship securely sandwiched between 2 pieces of cardboard via First Class Mail.
