Circa 1950 – probably post WW2 – Martin Gardner was the principle “magician” in a series of television shorts demonstrating tricks. These were designed to accompany an advertising campaign – e.g., Martin demonstrated a trick/illusion, then they cut to a “brought to you by Zingerman’s furniture store, where this week’s special is…,” followed by Martin revealing the trick.
Apparently, according to Martin’s son Jim, someone had the video files of these performances, which he loaned to a local magician years ago, and they were then lost. Now Jim is trying to find them, and has asked me to inquire on SWIFT when/where these videos were produced. New York? Chicago? – and who might have the originals.
Any suggestions on this inquiry will help.
