Marvel Comics is celebrating its 70th anniversary, and the company has been encouraging fans to vote for the best Marvel characters, single issues, etc. I played along by voting for the best comic book covers in Marvel history, though I only voted for 30 rather than pushing the 70 limit. I think these are all pretty great:
I came across this comic book cover recently at Marvel.com and I'd like to share it here:
Ms. Marvel #38 (Wolverine Art Appreciation Variant)
The Sentinels, monstrous constructions, signify the oppression mutants face in the X-Men universe. They are built to capture and control the mutant population, and they echo real human ignorance. But this cover art shows more than the terror of these machines. It shows an individual protecting his fallen comrade and friend. It focuses on the defiance of a few versus the unyielding authority of the many.
A great X-Men movie (there haven't been any thus far) would convey these emotions.
