Fred Mogubgub is primarily known for his television advertising work, but he also made underground short films that combined animation, illustration and live action, such as The Pop Show (1966).

The Underground Film Journal has recently uncovered that there was a previous New York Underground Film Festival — in 1970! This event is totally unconnected to the ’90-’00s era festival and featured a weeklong series of screenings in mid-October of that year, from October 12 to 19.
