OKay there was a book I looked at in a bookstore that I dont remember where it was a muppets arts and crafts book and they showed how to make gargoyles with milk cartons and just wondering if anyone knew what book it was, there are like 10 different muppet art books.

Also does anyone know if theres every been an art of henson book? Not just about the muppets? About his fantasy stories?
