About the image:
“Movie stagehands pushing a 400-pound pair of gigantic scissors on a dollie next to two men carrying a 21-ft. pencil, just some of the props that created the illusion of a dwindling hero for the movie The Incredible Shrinking Man at Universal Studios.” Photograph by Allan Grant, September 1956, Hollywood, California.
