Downs, T. Nelson. Autograph Letter Signed to Howard Thurston Regarding "The Art of Magic." Marshalltown, Iowa, March 27, 1932. On a plain sheet of paper (11 x 8 ½"), in black fountain pen, regarding the printing and copyright history of Downs' classic book The Art of Magic (1909). Downs explains that the first publisher of the book, W.G. Edwards, apparently unhappy with its sales, gave the printing plates to A. Roterberg, who then issued the so-called "spurious" edition. Later, the copyright passed to Arthur Felsman for an authorized second edition. This letter contains the additional tidbit that Downs was amenable to granting Thurston permission for another printing, an arrangement not widely known to have been conceived or explored.
