There is a cover of the magazine "Der Floh" with Twain as Diogenes around that time (actually several years earlier). I cannot hunt it down at the moment but I have a slide of it I am looking at right now. I believe I got it from either OUR FAMOUS GUEST by Dolmetsch ; or from Lou Budd's book, OUR MARK TWAIN.
