|From Buster Keaton: Cut To The Chase by Marion Meade|
I originally posted the top photo last year as a photo of CC and Buster Keaton but now that a clearer version of the photo has come to light (below), it seems this may not be Chaplin after all.
I think there is definitely a slight resemblance but taking a closer look I don't think it's him. Charlie had a longer nose and different hairline (I should have noticed that in the top photo). The folks over at the Buster's Boosters Facebook page seem to think the man with Buster is Paul Conlon. After seeing a photo of him I think they are right.
