You can't beat a bit of children's art can you? These are from a book I picked up a while ago from a charity shop. The book seems to be aimed at art teachers in schools and there's lots of nice examples.The book itself was printed in the 60s and I think it was probably published in Germany originally. As you can see there's a fine example of some boys on swings wearing leiderhosen! The trees drawings remind me a lot of Bryan Pearce's work. (He was one of those Cornish outsider art types from St.Ives).
