I SAW WHAT YOU DID

Original 9 1/2 inch by 7 3/8 inch Still of JOAN CRAWFORD in the 1965 William Castle Horror Movie I SAW WHAT YOU DID, based on the novel by Ursula Curtiss

Teenagers Libby and Kit have found a new way to entertain themselves: by calling up random strangers and tormenting them with a warning: “I saw what you did, and I know who you are. “, But when a man who has recently murdered his wife becomes their latest victim, the tables are quickly turned…and this wrong number may mean that their number is up.

The still is in very good condition with a synopsis once tacked to the reverse.
