Nude study, woman from behind.
 Signed in the negative "Studio J.Mandel Paris".

 Julien Mandel is a photographer whose biography is shrouded in mystery…sometimes he was born in 1893 in Poland, exiled to Brazil where he supposedly died in 1961 after his Parisian studio went bankrupt, or else he was born in 1872 in Alsace and died in 1935 in Paris…It is also said that it could be a pseudonym behind which the photographer Walery was hiding!
 In any case, Julien Mandel is one of the most celebrated photographers of female nudes from the early 20th century. Between 1910 and 1930, he produced a great many photographs of female nudes, which were published by the Neue Gesellschaft Photographische, Alfred Noyer, and Les Studios PC Paris. Equally talented in the studio and outdoors—he was one of the instigators of the "New Age Outdoor" movement—he also worked in film.
