This is a great shot of what Columbia Heights looked like in 1951 (according the the label). It’s the intersection where, today, you’ll find Wonderland and the soccer field behind Tubman. The streetcar tracks are running down 11th St. (looking left is south) and the street to the right, where the man is crossing, is Kenyon, heading back toward 13th St. You see Mays Farm Market, United Food Stores and and a Safeway.
Back to a better time in DC, long before crazy murder rates.
