This stamp is on an orphaned driveway apron in front of one of the many vacant lots (now a community garden) near the south end of South Francis Avenue. It’s on the east side of the street, just south of where Harton Street would have passed through if it had not vanished from this block at some point. There is another driveway apron (also no longer attached to a driveway) one lot south of here that has the same stamp, but in worse shape.

I tried to uncover the date from under the layer of caked dirt, but it doesn’t look like it would be legible even if it were clean. It seems to end with a 1 but that’s the most that can be made from it with any confidence. I wasn’t able to find any plausible “Terry” that this could be, either.
