These two cards were promo cards for the 1996 Skybox Marvel Motion set.
The cards are lenticular multi-image cards. These promo cards have a blank back. Both were inserted (randomly) into the $6.99 poly-bagged Direct Edition (comic store) variant of Sensational Spider-Man (Vol. 1) #11 which was cover-dated December 1996.
The cards are quite valuable now.
