This front cover from Pan Magazine was printed in 1919, just after the end of World War 1 and moving into the art deco age.  Probably thought of as "art decadent" by some people at the time, but I think she's lovely. 

Pan Magazine was a British publication, initially weekly, with a lovely cover, but quite lightweight content.  It was self-styled "A journal for saints and sinners" and a number of artists contributed to it. 

This cover is by Herbert Pizer, born in Stepney and son of a Polish Jewish immigrant. He sadly died at only 30 years old, from appendicitis. 

It's nothing to do with the coming of age of women actually, but given the zeitgeist I thought I'd make a connection.
