This is cool. In the May 10th, 1865 edition of the Baltimore Sun, this advertisement ran for the sale of a saloon at 98 Thames St. The streets have since been renumbered, but this is between Ann St. and Broadway St.

If you also know your Civil War history, May 10th, 1865 is also the day the war officially was declared over (though the last shots were fired on June 22nd).
