Three Generations of Norway, 1880s.

Care de viste of four Norwegian women. Taken in Arendal, Norway, by the photographer H.P. Nielsen. The original photo has some scratches and was of very low contrast, which accounts for the high grain in the photo above; their faces are nearly indistinguishable to the naked eye in the original. Appears 1880s.

Confirmation Class, 1890s.

Unmarked cabinet photo of unusual proportions. Appears to be a confirmation class from the late 19th century, but I was unable to find any explanation for the white, candle-like ribbons on the men.

Build Your Own Magic Lantern, 1910s

From the encyclopedic series The Book Of Knowledge comes this bit of practical information: "How To Build A Magic Lantern". These are what we'd call today a "slide projector". At the time, however, slides were images on largish pieces of glass, and the light source was an open flame. The instructions rely on store-bought lenses, but the body is completely manufactured by hand from materials such as brass, japanned tin, and wood. If the steampunks among you are interested in building a paraffin-powered LCD projector, this is a starting point.
