Made in 1969 by Marv Newland while at the Art Center College of Design in Los Angeles, California after Newland was left scrambling after the live-action film he was working for a month would not be completed in time for a school project - he had apparently missed a golden shot he needed.
So... he had a month to create this film... that he drew in his room... that was rented to him by Adriana Caselotti, who did the voice of Snow White in the classic 1937 Disney flick Snow White & The Seven Dwarfs.
It's not the best animation in the world, but comedy-wise, it is one of the best. It does feature the Call To The Dairy Cows from the William Tell Overture by Rossini, as well as the final piano chord from The Beatles' Day In The Life.
Say what you like - the cartoon has provenance!
I recall watching it on the all-night show on Channel 47 (yes, that number again) in Toronto, when it was introduced by Chuck the Security Guard and Ryerson The Camera Man at around 2AM back in 1980 or so.
I laughed so hard that I woke the whole house up.
I hope you will, too! And when the whole house is up, have them watch it with you!
Oh... and Newland moved to Toronto in 1970 and stayed in Canada.
