Covered is an awesome blog that features user-submitted remixes of classic comic book covers. The blog accepts submissions from any kind of artist, regardless of style or background. The stated goal of the site is to feature cover remixes by established artists as well as indie artists.
From the golden-age through today, from mainstream to indie cover, the more interesting it is., any comic book cover is suitable for a remix. Many different art styles are used for the remix covers; usually the more disparate the remix is from the original, the more interesting it is. Covered is curated by California artist Robert Goodin.
Here is a sampling of some of the comic cover remixes.
