The Library of Congress contains a digitized record of the “Turkestan Album.” It was commissioned by the first governor of Russian Turkestan—none other than the conqueror, General Konstantin Petrovich Von Kaufman.

It can be found here:  http://www.loc.gov/rr/print/coll/287_turkestan.html

It contains many photos of interest to the gamer of this period.  The “historical part” focuses on Russian military activities with battle maps and portraits of soldiers involved between 1853 and 1871.
