The listing, Washington DC Post Cards has ended.
4 unused/unstamped postcards of various Washington DC Tourist spots. Each card is about 5 ½ inches x 3 ¾ inches in size. The backs of the cards are shown in the second picture (any darker spots on the cards in the photo are just shadows!). Each card also states the sight in the back: this set includes Washington DC at Night, Washington DC Aerial, the Jefferson Memorial and Mount Vernon.
