16mm SOUND Film, large 12" reel, THE TROUBLE WITH TRASH, as pictured.  Probably a school classroom film for a science chapter on the environment???  Not sure.  Film has optical sound, but our vintage projector does not.  Leader for the film is damaged/sick and will need to be replaced.  We viewed about 2/3 of the film, but without sound to enhance the pictures.....well.....we moved on.  UN-packed weight about 5 1/2 lbs.  Please refer to pics for evidence of condition and email with questions.  Thanks!
