Where Flatbushites live Several apartment houses and other residential buildings, many parked automobiles, and many trees on both sides of street. Caption: "Where Flatbushites live--A pebble's toss from Flatbush Ave. can be found one of the tree-lined streets for which Flatbush is famous. East 21st St., seen from Dorcester Road, is typical of many in the neighborhood. Substantial private and two-family houses and modern apartments are 'home' for hundreds of thousands."
