GREEN & BLUE
I've been reading "The Heart is a Lonely Hunter" (excellent!) and have become very fond of it's cover - especially the type treatment for the title. Also using a green and blue color scheme is this poetry book on the bottom. I love the graphic illustration and the simple typeface. On the bottom right-hand side is the publisher's logo, which I noticed goes backward (the initials are BCC).
For an extensive visual database of book covers go to The Book Cover Archive, it's fantastic. It allows you to search by designer, author, genre, even typeface!
More posts on books to come...this will be a most literary week.
