I think this may be one of the sexiest photos I've seen for a long time. It is in a book by Sargeant Jagger, Modelling and Sculpture in the Making, from 1933, which is illustrated with numerous tipped-in glossy photos including this one of a nude maquette being constructed. Obviously, the body in the background is a fit and attractive one but there is something about the 'fact' of it being in the background, the lighting and the subject matter, all combined to make this a very arresting image indeed.
