"Time Piece" -- 1965 Avant-Henson

Posting this for no other reason than IT'S WONDERFUL: Laughing Squid gives us a YouTube embed of an ancient live-action Jim Henson short film called Time Piece. I'm curious about the "eighteen-month run" IMDb says it had in a Manhattan cinema. Which theater, and did it preface a feature presentation, as cartoons and newsreels once did? Or was it just shown at MoMA as an ongoing exhibit?

IMDb:

Dislocation in time, time signatures, time as a philosophical concept, and slavery to time are some of the themes touched upon in this nine-minute, experimental film, which was written, directed, and produced by Jim Henson-and starred Jim Henson! Screened for the first time at the Museum of Modern Art in May of 1965, Time Piece enjoyed an eighteen-month run at one Manhattan movie theater and was nominated for an Academy Award for outstanding short subject.

Wanting to know what Time Piece's Oscar competition was that year, I went to IMDb's page of the 1966 winners and nominees. For Best Short Subject, Live Action Subjects:

Winner:
	Poulet, Le (1962) - Claude Berri
Other Nominees:
	Fortress of Peace (1965) - Lothar Wolff Skaterdater (1965) - Marshall Backlar; Noel Black Snow (1965) - Edgar Anstey Time Piece (1965) - Jim Henson (I)

I wouldn't be surprised at all if these other shorts are on YouTube as well. Guess how I'm going to spend my Christmas!
