Fantastic 1926 Painting of Rudolph Valentino

This is a painting from Alan Hale Sr.'s collection. I am unsure who painted this, if anyone has any further information please let me know. I can tell you that Alan Hale Sr. was a well known actor and director from the teens to the 50's. You may know his son, Alan Hale Jr. as the Skipper from Gilligan's Island. This is one of the best likenesses I have come across in the form of a painting, especially from when he was alive. This is a fantastic, one of a kind piece that would be highly valuable and highly sought after.

Update on this item from Tracy: The only info I have on this was about 2 or 3 yrs ago I was contacted by Allan Hale's granddaughter asking me info on it. I had a 1930 or 31 movie magazine photo of Allan Hale standing in front of it. Mr. Hale co-starred with him in Four Horseman, and also was friends with Natacha. She had wanted him to direct The Hooded Falcon. The painting was not given to him by Rudy. The painting is easily identifiable as the "Last Portrait" photo, (cover of Emily Leider's book) That portrait was done in spring 1926 in Los Angeles, and that was his last sitting in Los Angeles, thus why it's called that. He did go on to do more in Chicago and NY which was his last. Being that it was done based on that photo makes it impossible to have been given in 1925. I believe Mr. Hale most likely commissioned this as a keepsake/memory after Rudy's passing in August 1926 The painting was auctioned off in Pasadena shortly after his granddaughter had contacted me. It was lumped in with a lot of old English furniture in the auction. I doubt it went for much. Hopes this helps with some of the true facts behind the piece.
