5 Elementary School Vintage  Film Strips & Cassette Tapes. In this lot you get all 5 sets which include filmstrip in the tubes with the matching cassette tape and pamphlet. These are all untested, but appear to have been well taken care of. I don't know anything about film, but I think they are 16 mm because they have small holes in the edges as seen in the last picture. The hang up bags show wear and 2 have broken handles. Look at the pictures for exactly what is included in this lot. Shipping is free in the USA.
