Michael Rothenstein was the son of the painter Sir William Rothenstein (1872-1945), and brother of Sir John, a former Director of the Tate Gallery. He was one of Britain's leading printmakers. After taking up printmaking in 1948 he subsequently worked in all the main techniques. As 'Jags' demonstrates, one of his innovations was to make relief prints from found wooden objects. Here Rothenstein used a section of wooden crate to print the main body of the image. He set a photograph of a car-transporter 'in the gap between the teeth'. Rothenstein's intention was to make a statement about the 'violently broken wood' and the violence which the car does 'to the countryside'.
