Marvel history is filled with grudges, the kind that aren't settled with harsh words and tough love over warm tea. Nope, they're settled with fists -- or sometimes claws, hammers or psychic blasts. WeLoveFine celebrates three of these ongoing rivalries with some new shirts featuring playbills for the brawl-to-end-all: Professor X vs. Magneto, Thor vs. Loki and Wolverine vs. Sabretooth.

I have it on good authority that they're hoping to do more of them, so who would you like to see next? Spider-Man vs. Doctor Octopus? Captain America vs. The Red Skull? Howard the Duck vs. Dr. Bong? Share your ideas in the comments section.
