 In the story "Treasure of Marco Polo" (Uncle Scrooge #64, 1966) by Carl Barks, the Duckburg embassy displays a flag of Duckburg, which consists of a white duck over a green field.However, in the Don Rosa story "His Majesty, McDuck" (Uncle Scrooge Adventures #14, Gladstone Aug. 1989) Scrooge gains a short-lived independence from the United States for Killmotor Hill, thus placing Duckburg within the United States.The most prominent landmark in Duckburg is Scrooge McDuck's Money Bin, a giant building sitting on Killmotor Hill (formerly known as Killmule Hill) in the center of town.
