Assassination Trivia

It appears to be an engraving of the D.C. City Hall where the civil trial of John Surratt, Jr. was held in the summer of 1867? The building still stands and recently had a make-over. It dates back to the 1830s, I believe; and there is a standing figure of Mr. Lincoln outside the entrance that is said to be the first memorial to him, being dedicated on April 15, 1868.
