John Snyder’s Gammatration-Cosmovision: less than 50 made: circa 1955

$350.00 $299.00

John Snyder was a genius. Next to Al-Jo this is his most desirable item.  It is the penetration of a signed card and then the imperceptible transposition of a signed card with an indifferent card. I have photographed the ad for it.  It is in very good condition as shown. Complete with the original box which has done its job of protecting the equipment for the past 70 plus years.  Hallmarked with the Snyder name. With instructions. Scarce!
