Fascinating. An etching purporting to be of Hitler and Lenin playing chess in an attic in Vienna in 1909 is being put up for auction in England. The artist, Emma Goldschramm, claimed to have been Hitler's art teacher and to have hosted a political salon at which on this occasion the two chess opponents were present. Now, I did a lot of Hitlerian research for my novel The Adorations, which has several scenes set in Vienna around 1909 in which Hitler's a character, and I found no evidence that he a) played chess; b) met Lenin; c) wore a suit, except to the opera; or d) attended political salons, especially in Jewish households. He may well have run into Trotsky, who frequented the Cafe Central, and there's a titillating scenario in which–in about 1909, as it happens–he gets into a shoving match with another scruffy young bohemian on a Vienna streetcar and a tussle ensues, after which young Hitler gets off, shaking his fist and shouting "You haven't heard the last of this!" at the other scruffy bohemian, who is (wait for it) young Stalin, in town for a secret Bolshie-spy meeting, presumably with the chessplaying Lenin. 

Plus, Lenin was egg-bald by '09, and Hitler looked more like a cross between Marcel Proust and Charlie Chaplin than he did the future Fuehrer. But who knows? History's a grand opera, and the composer's half-mad.
