KELLAR, Harry (1849 ? 1922). Kellar ALS to Harry Houdini. Dated Jan. 24, 1921 in Kellar's own hand, he writes to Houdini on his trademark lithographed letterhead regarding a range of interesting topics. In part: ?Hearty congratulations on your being called to lecture before the Club of Odd Volumes [sic] of Harvard College ?" ??why should they call it Kellar's match trick? I only spoke of it [to] Thayer & then I told him it was Houdini's trick." He concludes by discussing Alexander: ?I wrote to Alexander & advised him to cut out the exposes of other methods for doing the Crystal Gazing ? He said he ? never exposes anything he did not originate. In other words he did not expose other's inventions." One folded 8vo sheet, boldly SIGNED ?Your friend Harry Kellar."
