At least I think it’s 1941. That’s what it looks like in person. It’s an extremely worn DPW stamp (I recognize it by the shape and typography of the letters), located on the east side of Regent Street (200 block) between Kalamazoo and Michigan. Funny how unevenly they have worn, given that there are 1930s ones on the same block that are much more legible.
Tired of Regent Street stamps yet? I hope not, because you’re probably going to get more of them. How about Department of Public Works stamps? Same there; I want to see if I can figure out when they transitioned from one style of stamp to the next over the years.
The slab is a small one, odd sized. You run across truncated ones like this, both older and newer, and I’m not sure how they come about.
