box vintage antique slides they are mineral slides. Old black adams box. box has the register in the top of the lid the box Is in ok condition. See pix. Lots of slides. Box about 50% full. They are not perfect_ in old vintage condition. Tons of different slides all sorts of mineral samples. Top of box has pencil notations that I have no idea what they mean. Some slides have areas circled. I have no idea.
Also some have come off of the glass slides themself.
**I think they are from the 30\'s-40\'s I had a few boxes and one had a letter that was dated april 1930 they were found all togeither so assumimg from then**
