From the great Bookslut, I learned about this Slate experiment where they created pulp-like covers for classic books. The artists used classic pulp novels as inspiration and treated books such as Jane Eyre and Animal Farm to new cover work.
Here are some of my favorite pulp covers from the Slushpile.net library.
love that LOOK BACK IN ANGER cover. like those music video directors who take the lyrics of the song as a shooting script: pure comedy.
