i did this cover a while back, and it's finally going to be released. the book is a great read, and it was optioned by Spike Jonze, so read it before it hits the big screen. below is the original painting before design. i painted the balloon separately, so it was added on digitally along with the type. this is the final design. i love what the art director did with the final. kudos to paul buckley for his design skills.
i've added the amazon link below, just in case you were interested in picking it up.
