Portrait of Frederick II of Prussia by Friedrich Anton August Lohrmann after Anna Dorothea Lisiewska, 1784-1786 (PD-art/old), Zamek Królewski w Warszawie (ZKW), one of the portraits assembled by Stanislaus Augustus for his Conference Room at the Royal Castle in Warsaw
Uniform worn by Frederick II. of Prussia during the Battle of Kunersdorf (today Kunowice) in 1759 (Prussia lost). Remarkably humble, compared with the bling bling sported by his fellow monarchs (I'm looking at you, Louis Quinze...) And the man didn't just send his soldiers to battle, he risked his own neck as well. See that rip on the left side, below the fourth button? That was a bullet which luckily bounced off the royal snuff box (or so the legend goes).
