These are shots from the film screen.
Two stills from a Sesame Street film R. O. Blechman produced in the early 1970s. One of around five films he produced at this time for Children's Television Workshop.
The witches are reciting Shakespeare and making soup with letters.
These pictures mark the first time Blechman worked with Ed Smith. From this point on the quality of Blechman's films will change considerably.
Nice art production too. Sarah Calogero, probably.
