Update: This is David Warfield, one of the most noted figures of the American theater in the early 20th century.
Just a reminder on how this works: I post the mystery photo on Monday and reveal the answer on Friday. To keep the mystery photo from getting lost in the other entries, I move it from Monday to Tuesday to Wednesday, etc., adding a photo every day. I have to approve all comments, so if you're wrong your guess will be posted. If you're right, you'll have to wait until Friday. There's no need to submit your guess five times. Once is enough. The only prize is bragging rights.
Here's another photo of our mystery fellow. He has been correctly identified by Claire Lockhart, Eve Golden, William, Zapgun and Dru Duniway. Congratulations! Please also congratulate Dewey Webb, Richard Heft and Sam.
Update: Another picture of Warfield as Shylock.
David Warfield ... and a flea circus, a Times reporter strolls Los Angeles, 1909.
Above, an undated photo. At left, David Warfield died in 1951, 26 years after retiring from the stage.
Check back next week for another mystery photo!
