I was on ffffound earlier today and I stumbled on the Letraset USA book cover. I researched it to find out more but didn’t get very far. I did run across a European blog called Evasion. The Letraset cover was a part of a post called 100 Design Book Covers on the blog and I was really amazed by the epic selections they had presented. These above are my favorite of the bunch. I really like the abstraction and colors in the last one.
