As somebody who grew up in and around Washington and environs, it's neat to see that store which was located on F Street, N.W. F Street was Ground Zero for the downtown shopping district for much of the 20th Century, and I have vague memories of begin taken downtown (late 50s/early 60s) around the holidays to "window shop." The major department stores were all in that area and it was the era where folks came from all around to stroll and look at the holiday decorations.
Real "A Christmas Story" stuff!
