A Trip Down Memory Lane is a 1965 experimental collage film by Arthur Lipsett, created by editing together images and sound clips from over fifty years of newsreel footage. The film combines footage from a beauty contest, religious procession, failed airflight, automotive and science experiments, animal experimentation, skyscraper construction, military paraphernalia, John D. Rockefeller and scenes of leisure, Richard Nixon and scenes of war, blimps and hot air balloons, and a sword swallower. Lipsett envisioned his film as a kind of cinematic time capsule for future generations.

A man struggles with his past relationship, and decides to go to the park to let go of his troubles.
