15th and G St. NW in 1911

View from Pennsylvania Avenue NW looking east towards the buildings on the east side of 15th Street as well as the southeast corner of 15th and G Streets. Streetcars and horses and wagons are on streets.

I’m trying to make out where this is today. 15th, Pennsylvania, and G St. don’t really intersect. Can you help out and add your ideas below in the comments? I think we’re looking down Pennsylvania, to the left is New York Ave. and in the middle going away is G St.
