In 1909, Alfred Carlton Gilbert, a magician, and his friend John Petrie founded the Mysto Manufacturing Company in Westville, Connecticut to provide supplies for magic shows. In 1916, the name of the company was changed from the Mysto Manufacturing Company to the A. C. Gilbert Company. Their “Mysto Magic” magician’s sets were marketed from the 1910s until the 1950s. The sets contained a variety of objects including interlocking rings, playing cards, and a magic wand.
