This handwritten mark is on the west side of Leslie Street’s 500 block, between Kalamazoo and Elizabeth. Is it a contractor’s mark, or graffiti? It could easily be either, but guess is the former, based on its placement.

I can’t seem to find out anything about C.H. Peel, either as a contractor or as a person, but my guess is that this is either Charles Hubert Peel or his son Charles H. Peel Jr. Both lived (and died) in Lansing according to Find A Grave, and both were plausible ages in 1961. The father lived 1907-1988 and the son lived 1932-1988. Sadly, they died close together, first Charles Jr. in May 1988 and then Charles Sr. in November that year.
