I couldn't resist the cover on this 1920s novel published by Ernest Benn. The jacket suggests that this may be a mysterious stranger (clothed) who turns up at a Dorset pub one night and drugs a load of Wreckers and whisks them off to a life of piracy on the high seas. Even the blurb on the book seems to be acknowledging the nonsense of it all. I imagine you would have to read it to discover why the other chap is naked!
The drawing is actually rather accomplished and initialed E.W., which I feel I should know, but it's not coming to me at the moment.
