I’m not even going to search for a photo. But do a quick and dirty post for Metropolitan African Methodist Episcopal (AME) Church at 1518 M St NW. In 1957 it was a big church, with 1200 members in 1957, with about 400 showing up on any given Sunday. The professional majority were skilled laborers, followed by Professionals and white-collar members. It was and is, as far as I can tell, still a Black church. It does not give a breakdown but claimed many members lived in the Northwest Urban Renewal area under study at the time.
