The refrigerator in the school was like the one my neighbor Edith had. They got it when they built the house in 1951.
GM usually went all out for their promo films, using a top professional cast. Lots of "the face is familiar, but can't recall the name" actors. Wish I could think of who plays Grandma, as I remember that actress in old movies and TV shows. The school board member in the hat was also in lots of shows. Some well known performers go their start in these industrial films.
