So look out — stuff is about to get real interesting up in here.
Above, maybe my all-time favorite photo of Abraham Lincoln (click to enlarge). The photo was taken by famed Civil War photographer Matthew Brady at Antietam, Maryland, on or shortly after September 17th, 1862 — the first major battle fought on Northern soil and the bloodiest single day of the entire war, with over 23,000 casualties. Pictured with Lincoln are General J.A. McClernand and "Major" Allen Pinkerton, the head of Union Intelligence (which would become the Secret Service) and of the infamous Pinkerton National Detective Agency.
