Pinscreen. Circa 20 minutes. 1973. 1 x 16mm mag plus 1 audio cassette of the material. Alexander Alexeiff is talking with occasional interpolations from NFB animators. There is no slate so I (Don McWilliams) assume that it is wild sound recorded at the time of Alexeiff’s workshop and installation of the pinscreen at the NFB. Sound is poor, muffled (air-conditioning hum?) The content is good. Tail Out. None of the ¼ inch original synch recordings seems to exist.
