Catulle, Charles. Archive of Charles Catulle—Harry Blackstone Correspondence. Discussing the fabrication of illusions and props for the Blackstone show, built to order by Catulle, a little-known manufacturer of magic effects based in Cambridge, Mass. Catulle writes to Blackstone regarding a “Wine Table,” costumes for a switch illusion, a Sarcophagus illusion, and the Radio Cabinet. One letter discusses Houdini’s recent appearance in Cambridge on his final tour. Several letters demand payments from Blackstone, and one detailed accounting accompanies the letters. Letters date from 1926 and 1927, most written on Catulle’s letterheads (some rubber-stamped with the line “builder of the best fun houses”). On the reverse of one sheet, Blackstone has sketched out a version of Amac’s Find the Lady effect, and other illusions, in pencil. Early, fascinating, and important correspondence.
