In this New York Public Library video, assistant curator Charles Cuykendall Carter shows off Les Portes Fermées, ou, Les Doubles Surprises (The Closed Doors, or The Double Surprises), a new acquisition of the Pforzheimer Collection. The small nineteenth-century French toy book is comprised of seven miniature romance and trickery stories, each accompanied by an illustration with a door flap opening onto a surprise illustration that appears when the card is held up to the light.
