The 2nd series Steppenwolf proof card showcased in this entry features the "Fan Club Offer" banner on the front. Toy packaging color correction, text proofing, and other reviewing technically take place during the packaging production process's cromalin stage. Super Powers proof cards, however, sometimes contain signatures and review dates indicating they underwent some level of approval/review. Super Powers proof cards often exhibit a punch style deviating substantially in shape from their production counterparts. Some exhibit punch shapes akin to those found on vintage production Star Wars blister cards, while others vary less drastically. Proof cards are frequently used for carded samples, like the 3rd series Red Tornado shown here, where the bubble is hand applied to a proof card.
