If you don’t know what a lantern slide is, Lantern Slide Collection has a very good overview. Basically, they are captured/projected positive (vs. a negative) images on glass plates.
In terms of look and technology, they are a cross between a high quality photocopy and photograph. Many of these are handtinted, which gives them a beautiful artistic and sometimes dreamy look.

This technology predates photography as we know it. The American Museum of Natural History has been sharing images and information about their Lantern Collection on Facebook.
Not only is this a fascinating glimpse into our history and culture, but also into an early technology. So, wander over there and take a peak. Enjoy!
