Vintage 2" by 2" Slide Lot ~ Trains and Movies ~ 40 Slides

Description

Vintage Tray of 40 - 2" by 2" slides. I think these are glass slides but I'm not 100% positive, they aren't plastic. They seem a little heavy. When I purchased them, I was told they were glass.
Interesting group! A lot of train slides. There are other slides that make me think some are from an old movie or play. The slides are numbered but there are no descriptions.
They all seem to be in good condition. They are older, so there may be fading, or fingerprints. Overall they are nice and clear.
Please refer to pictures.
Slides and tray come in original box.
