I have seen the Compton and Dry pictorial St. Louis used for a variety of historical purposes, but I have yet to see a full comparison of the pictorial St. Louis in 1875 with what remains today. Each day a new plate will appear in the order of their appearance in the Compton and Dry map, followed by an edited version in which the remaining buildings (as far as I can tell) are highlighted in blue. All images are from the Library of Congress downloadable map.
