This is pretty confusing: "John Maloof purchased a box of never-seen, never-developed film negatives of an unknown ‘amateur’ photographer for $380 at his local auction house."

If they were negatives, they were developed. Was this undeveloped film? Or do they mean "never-printed negatives"? How would they know?

And the illustration above this text is a bunch of Kodak slide boxes, not negative envelopes. I never got negatives back in boxes like that. So I'm confused about what is what here.

Nonetheless, the photos are wonderful!
