Oho! Now what do we have here? A DPW variation I haven’t seen before – sort of. It’s on the west side of North Magnolia Avenue just north of Michigan. The style is similar to the 1940s DPW stamps, but it says Lansing DPS instead. So, around 1950 Lansing apparently went from having a Department of Public Works to having a Department of Public Service. Today we have a Public Service Department, but the stamps specify O & M or Operations and Maintenance, one of the divisions of Public Service.
