I remember photographing Sumner School years ago and saw it again on our way to National Geographic. The building at left definitely wasn’t there at the time.

The Charles Sumner School, established in 1872, was one of the earliest schools for African Americans in Washington, D.C. Named for the prominent abolitionist and United States Senator Charles Sumner, the school became the first teachers' college for black citizens in the city and the headquarters of its segregated school system for African American students. It currently houses a small museum, a research room, art exhibits, and the archives of the District of Columbia Public Schools.
Best to view in "Original" because other versions resized by Pbase are decidedly unsharp.
