Another favorite, and this one, like a couple of earlier Canal Month posts, shows a canal scene right by today's Amazon Whole Foods.
From the Brooklyn Eagle, January, 1946:
Nine men at bridge railing looking down on debris on frozen water of Gowanus Canal; bare trees, telephone wires, and truck in background; retaining walls and patch of weedy vegetation in foreground. Inscription: "Bridge over Gowanus Canal at 3rd Ave., btwn 3rd & 4th Sts. from which two youths today caught sight of four guns (two revolvers and two automatics) and 200 rounds of ammunition on the canal ice."
