This corner-placed stamp is on the west side of South Hayford Avenue midway between Prospect and Michigan. The contractor is definitely Smith, probably O.M. [something] Smith, and tentatively O.M. Smith. It does look like an M to me. There is another similar stamp on this block but unfortunately the second letter on that one is at least as worn. Although at first glance this looks like 1982, closer inspection shows it is 1962. (I find that is often a hazard of the fonts they like to use for numbers; they tend to have a highly curved 6.)

I haven’t been able to find anything out about the contractor. I can find from the Lansing State Journal that an O.M. Smith was living in Lansing in the 1940s, but nothing about a cement business. Perhaps I’m wrong about it being O.M. Or perhaps I just haven’t done enough research yet. (I can’t help thinking of the character One Million, who goes by “O.M.,” from the Rankin-Bass special Rudolph’s Shiny New Year.)

A tween-aged kid was practicing basketball solo in his driveway, making a go at doing flashy moves like spinning around as he approached the basket. I glanced away as I passed in order to avoid embarrassing him but honestly it was pretty endearing. It reminded me of my brother messing around on his skateboard when we were that age. You can make out just his legs in my photo above.

Update 3/21/21: I now know that it is O.V. Smith, as I happened across his name in the classifieds while research a different contractor!
