Found this mention in a book industry blog:
9 January, 2008
Picture book Artist and illustrator of the upcoming picture book BUMP IN THE NIGHT Edward Hemingway's BAD APPLE, about an apple, who befriends the worm living inside him, again to Susan Kochan at Putnam, by David Kuhn of Kuhn Projects (World).
So I guess Ed is going to come out with another children's book next, called "Bad Apple", to be published by Putnam.
The original context is here.
