A friend of mine just pointed me at this site. Marvel has commissioned several "art appreciation covers" for its Avengers line.

Some of these are fantastic. Some are hilarious.

I recognize most of the source art being used, but I still want to give kudos to Marvel and the artists of these covers for their sense of humor, ingenuity, and the skill of execution.
