I don't think i have ever seen an illustration presented underwater until i stumbled across Saul Steinberg's 'Girl in Bathtub' 1949. His photo-cartoons, in which objects are drawn upon and then photographed, can be captivating. In the early 1950's, he drew on objects or entire rooms and had a photographer document the results. This has got to be one of my all time favourite pieces of art because the idea is so simple but just amazing! I am going to have a go at making my own and then upload them onto my blog.
