Origin. A theory as to the origin of the jack-in-the-box is that it comes from the 14th-century English prelate Sir John Schorne, who is often pictured holding a boot with a devil in it. According to folklore, he once cast the devil into a boot to protect the village of North Marston in Buckinghamshire.

Manufacturers first produced the box in wood, then printed cardboard, and most familiarly in lithographed tin in the 20th century. Jack-in-the-boxes initially featured the familiar clown in papier-mâché, then bisque, then celluloid, then plastic.
