As always, the illustrations by Eric Carle are exceptional, as is the "think outside of the box" message. The first blue horse I ever saw was a very very long time ago. It was in an art class at Western Michigan University in Kalamazoo, MI in 1967. The man who painted it was Franz Marc. It was a "think outside the box" moment for me back then. I was delighted to learn that it was Franz Marc who also inspired Eric Carle!
