7-Eleven (Series 2, Marvel Plastic Cups)

In 1975 & 1977, Marvel licensed its characters to 7-eleven for use on their world-famous Slurpee cups. The first set had some 60, while the second set had 29 (or more) different characters. Naturally enough, each set included Spider-Man (three in '74, two in '77). Another (glass) set was issued (also in '77). The glass from that set is listed separately.
