Here is a curiously unsigned date stamp from the north side of Prospect between Bingham and Pennsylvania. Most of the 1940s stamps I find are from the Department of Public Works, so I am inclined to suspect their hand in this. If so, I am sorry they didn’t complete the marking, as I have no 1949 DPW stamps recorded, and I am trying to figure out when they switched to stamping DPS instead. The latest 1940s stamp I have found is a 1945 which probably says DPW but that part is worn enough to be unclear. The next prior one I have is a clear 1944 DPW stamp. After that it skips to 1950, at which time they were now identifying themselves as the Lansing DPS.
