I returned to an old-looking but illegible stamp I had previously done in 2021, hoping that the time of day or the wet pavement might have made it visible. Unfortunately, I still can’t make it out (except for “Lansing, Mich”), although fussing with the contrast a bit made it tantalizingly close.
The paired stamp a bit north is equally illegible, if not more so. These are on the west side of North Foster Avenue between Michigan and Vine.
