Tales to Astonish No. 93 (1967)
Marie Severin beautifully teases out the subtleties of the Hulk's relationship with the Silver Surfer in this gorgeous cover for the first meeting of two lonely titans. Clearly, the Hulk and the Surfer are in the middle of a fight the Hulk's actually trying to steal the Surfer's board. But they're also riding together on that board and the Surfer's calm demeanor indicates a deeper understanding. The actual story, written by Roy Thomas, remains one of my favorite.
