This photograph of Prince Felix Yussupov, Princess Irina of Russia, and their daughter Princess Irina Felixovna Yussupova in about 1916 is from a posting at Alexander Palace.org I believe it originated in Yussupov's book "Lost Splendour" and was possibly printed as a postcard during World War I. Because of its age, I think it's probably in the public domain. If I'm wrong, please delete it.
