Harry Kellar - The Real Wizard of Oz?

 Students of magic history are probably familiar with Harry Keller (b. Heinrich "Henry" Keller 1849-1922), one of the great American illusionists.  While his fame has since been eclipsed by that of Harry Houdini (with whom he was close), and his chosen successor, Howard Thurston, in his day, Kellar was the best known illusionist in the world.  His fame was such that his advertising media, like the poster seen below, bore only his name "Kellar" -- there was no need to note that he was a magician or illusionist, as everyone knew.   Kellar's lithographic posters, produced by Strobridge litho, are among the most beautiful and highly sought after magic collectibles.
