The listing, 1956 1 1/2 cent Mt. Vernon Plate Block has ended.
Brown/Carmine MNH SC#1032 Liberty Series.
These are very unique plate blocks if you know the history of them. Here it is:
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 hid brother and sister-in-law. He applied scientific methods to farming, and established one of the largest distilleries in the nation. George and Martha 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.
