That painting was used for the cover of the paperback of "The Exploits of Sherlock Holmes" by Adrian Conan Doyle and John Dickson Carr. I still have it. "Never before in paperback!" Pocket Books $1.95. I remember when I saw it on the wire racks at Woolworth. I thought at the time that Holmes looked a bit like Patrick Macnee.
Yea, he does look a little like Patrick Macnee.I guess he couldn't get away from using a calabash pipe.
