Thanks to GoDCer Mike for sending in this family photo from 1955. Below is the note he send:
Dear Ghosts of DC
This photo surfaced in our family a few years ago. It was taken in 1955 and shows my parents, Sue and Joe, the year before they were married. Sue worked at the Pentagon and Joe was stationed at Vint Hill Farm Station. I guess there were street photographers who mailed the photo in the souvenir sleeve after it was developed.
They don’t have to do that anymore, do they?
