These images are part of a set of lantern slides held by D.C. Public Library. They were purchased in 1944, a collection of 1800+ lantern slides and glass plate negatives purchased from photographer E.B. Thompson for $1,000. Two hundred and thirty of them are available in this Flickr Commons photo set. The collection has many interesting historical photos of the goings on in the US Capitol including Pauline, a pet of President Taft, grazing on the White House lawn.
