 These so-called "Livingston Butchers" today command premium prices among collectors, the five stereo versions being the most rare and valuable of these.In April 2006, Heritage Auction Galleries sold one of the sealed mono "Livingston Butchers" at auction in Dallas for close to $39,000.An extremely rare original "first state" stereo copy that was not from the Livingston collection was presented for appraisal at a 2003 Chicago taping of the PBS series "Antiques Roadshow".
