Nekko Omar Perfect Mystery. Chicago: W.J. ?Doc? Nixon, ca. 1932. Wooden cabinet hangs between two short uprights. Barred sides allow a clear view inside. Front and back doors are opened and closed and a production is then made from inside. 20 ?? high. Finish worn. Scarce. Constructed during Nixon?s time in Chicago and after his attempts at vaudeville stardom, first with Okito?s act, and later with his more successful turn presenting ?Where do the Ducks Go?? Nixon manufactured a select line of props at high prices, including a bowl production and checker cabinet; all of his products are uncommon.
