Beginning in 1991, Marvel started publishing an annual series of Swimsuit magazines, full color pinups of heroes and villains in skimpy beach ware. Modeled after Sports Illustrated, each issue took place in one of Marvel's fictional locations. The first issue took place in the Savage Land. Here's a trio of pinups from 1991 featuring the Avengers.
Captain America and Diamondback. Although it's not signed, I believe this was drawn by Michael Golden! The other Swimsuit issues often featured Cap in a red white and blue speedo, but this was probably the best one. If you like that sort of thing...not that there's anything wrong with that. Diamondback was Cap's gal pal during this period. I have fond memories of her. She's featured in all the other swimsuit issues as well.
Thor and Sif relaxing as Loki lurks in the background. Drawn by Ron Frenz and Joe Sinnott. Thank goodness that Frezy didn't draw Thor in a speedo. Hard for me to imagine a Thunder God on the beach in a resort: Verily, I'd like another Pina Colada. What would Loki do? Make it a virgin?
Here is one of the best illustrations in all these swimsuit specials: Scarlet Witch by Mike Mignola. She's sexy without being voluptuous and Mignola's use of shadows and blacks really makes the magic seem wonderful. Nuff said.
