Kenner Canada produced two 12-Back card styles for the twelve 1st series action figures. The carded Penguin shown above illustrates one of the two styles: the "Free Figure Offer" variety. The "Free Poster Offer" represents the other Kenner Canada 1st series card style. While Kenner required submission of five proof-of-purchase seals for Steppenwolf redemption by June 1, 1985, Kenner Canada required submission of only three proof-of-purchase seals by September 1, 1985. Kenner Canada's cardback offer details make no mention of the Darkseid record and rebate coupon inclusion, which may explain the lower proof-of-purchase seal redemption requirement. Unlike Kenner, Kenner Canada opted against branding the rear card face with new Steppenwolf promotion offer imagery. Instead the "Free Poster Offer" advertising section simply featured updated text pertinent to the Steppenwolf offer. To date I've been able to document 11 of the 12 first series characters in this packaging style. It's quite likely the currently undocumented Wonder Woman saw release on this card style and has simply elluded me after all these years.
