Double-sided poster invitation for a disco-themed party thrown by Nancy and Bill Samuels of Prospect, Kentucky. The back of the invitation shows a map to the Samuels' house and silhouettes of disco dancers beneath the words "It's spine-tingling. It grooves you. It's..." The front completes the phrase with "DISCO, BABY" and shows a picture of the hosts posed in disco attire against a psychedelic background. Includes a 3" x 5" card asking guests to RSVP due to "a need for heightened security."
