Jasper Johns (1930-present) is an American artist who has worked in drawing, sculpture, and printmaking. He has been a major influence in minimalism and pop art. He is most known for his images of flags, maps, and targets.
I remember seeing the print of the coat hanger a few years ago and I was immediately attracted to the line quality and the effectiveness of his figure ground composition. Johns has many prints and, in an interview, talks about how printmaking brings an experimental quality to his work. It also introduced the idea of mirror image and layering often seen in his work.
