Mysto Magic Company
Mysto Magic Company was founded by amateur magician Dr. Alfred Carlton Gilbert and magician John Petrie in 1909. They established the Mysto Corporation to sell a series of childrens' magic sets, under the "Mysto Magic Sets" label. An entire range of "Exhibition" sets were developed, from beginner to advanced, bringing the Golden Age of Magic into the parlor.
It was one of the first mass merchandisers of magic toys.
