The Darkseid proof card featured in this entry highlights the sleek 33-back packaging style. The focus shifts heavily towards the character artwork given the absence of any offer/mini-comic banners and artwork usually located behind the figure area. These aspects make 33-back proof cards popular with collectors.
Toy packaging color correction, text proofing, and other reviewing technically take place during the packaging production process's cromalin stage. 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 production Star Wars 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.
