This was in a box with a lot of other movie policy trailers. I am not sure if this is a "silence is golden" style policy trailer, or a BTS mini-trailer on the making of movie soundtracks.

This was acquired in a storage locker auction of a man that was a manager at multiple movie theaters during his career. He was also worked in film restoration. He had a huge mix of trailers from his time working. This was in the lot. I have never tested it on an movie player, I don't have the gear. It looks good overall, but will have wear from being rolled up for many years in storage.
