You have to see this Museum of Modern Art site to believe it, because you usually have to pay for things like this. Print technology has changed the world and here students from 7 to 17 can enjoy being taken through the history and techniques of prinmaking - you can even carve out a woodcut online. You can also admire the work of artists such as Durer, Lautrec and Warhol. Under each technique there is a gallery of masterworks in that genre.
