Turner is @ former Tate Gallery (last time I visited it was called that), now it is called: Tate Britain, same location different name, but this is a book that was first published in 1971 by Phaidon, that I found in the trash… so this should actually be: Not On The Wall XXVI. As in: Not On The Wall.
