This isn’t a sidewalk or even a driveway. It’s a concrete pad on the Prospect Street side of the old L.F.D. No. 4 fire station (now home to the Davies Project). The building faces Bingham Street at the northwest corner of Bingham and Prospect.
It appears that at some point the concrete was covered with a layer of asphalt that has mostly worn away, letting the old stamp resurface. I like how it looks. 1942 is an especially common year for DPW stamps in the neighborhood, usually using the “old style” (1910s- early 1940s) stamp.
