This is the art for a play titled "The Way of the World" by William Congreve.  The show opened at Soulpepper Theatre in Toronto on July 2 and runs through August 2.  Here is a description from the theatre's catalogue:

"William Congreve's Restoration masterpiece is one of the wittiest, sauciest, and most loved of English language comedies.   Peopled with a wonderful variety of characters, the play is particularly distinguished in its creation of the unforgettably assertive women.  A rare commodity: a very sexy, very smart and very funny play."
