This may be old news to some but it was new to me and I thought these covers were really fun!
http://www.comicsalliance.com/2012/05/01/avengers-fine-art-variant-covers/?a_dgi=aolshare_facebookIn honor of The Avengers movie, which opens in U.S. theaters this Friday, May 4, Marvel Comics released 14 special variant covers across its comic book line in April, each depicting Earth's Mightiest Heroes in the styles of some of history's greatest artists like Rembrandt, Michelangelo, Monet and Pollock, just because. The comics artists creating those visions include Gabriele Dell'Otto, Michael Kaluta, Alex Maleev, Greg Horn, Khoi Pham, Christian Nauck, Mike Del Mundo, Stephanie Hans, Steffe Schutzee, Charles Paul Wilson III, Joe Quinones, Julian Totino and John Tyler Christopher. Many of those works found their way into ComicsAlliance's picks for Best Comic Book Covers Ever (This Month) for April, and you can see the full collection of The Avengers "Art Appreciation" variants after the cut.
