Notes:
Glasses that create the illusion of "X-Ray" vision, allowing you to apparently see through solid objects. Sometimes sold as X-Ray Spex. Sold by Slimline Company of Newark, New Jersey; Honor House Products; Rembrandt Co.; Big 3 Ent.; Elbarr Distributors; Standard American Suppliers, Inc.; A.T.H. Co. of Stroudsburg, Pennsylvania; Gandalf Products of New York, New York; and perhaps others.
Based on an older device called Wonder Tube and popularized by Harold von Braunhut. Aqua-Spex and Hypno-Spex operated by similar principles.
