This is an uncut proof sheet for Kenner’s MASK Adventure Packs. Prototype proof sheets like these were often used to make final corrections before the cards were printed in mass quantities. The sheet measures 28 1/2″ tall by 20 1/2″ wide. The cards are printed on front and back.
The Adventure Packs were released in 1986 and were a way for Kenner to expand the MASK line. They included a MASK figure along with several themed accessories. The sheet has the backer cards for Venom’s Revenge, Jungle Challenge, Rescue Mission, and Coast Patrol.
