Located on the banks of the Potomac River, Mount Vernon was George Washington’s plantation home in Virginia. Completed in 1743, the wooden neoclassical Georgian mansion was situated on 4,200 acres of land. Washington inherited the home upon the death of his brother and sister-in-law. Washington applied scientific methods to farming, and established one of the largest distilleries in the nation. George and Martha Washington are interred on the estate, which remained neutral ground for both sides during the Civil War. The structure (and a portion of the property) was designated a National Historic Landmark in 1960. The Liberty Series Issued to replace the 1938 Presidential series, this patriotic set of stamps honors guardians of freedom throughout U.S. history.

Leaders of the 19th century including Monroe, Lincoln, Lee, Harrison, and Susan B. Anthony make an appearance. The 20th century is represented by Teddy Roosevelt, Woodrow Wilson, and General Pershing. The Liberty Series also features famous locations important to America’s democratic history, such as Bunker Hill, Independence Hall, and the Alamo.
