lay-out shot at the

The photogprahps below were taken by Helmut Newton at the George V Hotel in Paris.   They are part of his  "World Without Men" series.   The photo of Gia below on the left, posing with a "male," model is considered to be a work of art.  It's called, "Woman Into Man," and can be seen in many art photography books.  You can see "Woman Into Man," at the Staley-Wise Gallery  on line.
This is the best scan I could get of the two page photo below.
