Each of the School Prints lithographs had a drawn, or clever trompe l'oeil, frame so they could be easily pinned up and save schools the cost of actual framing. This is Tractor (First Series, no 3) by Kenneth Rowntree (1915-97), one of the Great Bardfield artists. Rowntree's skills as a muralist meant he understood art for public places and this, together with his interest in everyday scenes, made Tractor one of the most popular in the series.
