Yesterday I read Flavorwire's great interview of graphic book cover designer Rodrigo Corral. I am sure you have seen his stuff on show-stopping covers like Junot Diaz' Wondrous Life of Oscar Wao and James Frey's Million Little Pieces. Incredible.
I felt I had to share some of his other great designs, as featured on the fabulous website The Book Cover Archive. Check out Rodrigo's page here and the Archive's super cool blog here.
