Lobby card no. 4 depicts the scene where Al Chop (Towers) awakens to a newspaper headline trumpeting the appearance of UFOs over Washington, D.C. overnight in the summer of 1952. A week later, they'll return.
This particular scene was also featured on the reverse side of the box housing MGM Home Video's VHS release of "U.F.O." in 2000, displayed with the same blue tint as the front.
