This is on the north side of Michigan between Fairview and Magnolia, out in front of the MetroPCS that looks like it used to be a rental car place (because it was, but more on that in a future entry). At some point, the sidewalk here was narrowed, leaving only half of this stamp behind. It looks like it was chopped off to make room for a garden or street tree, though all that’s here now is a weedy patch. I had to pull up a mat of encroaching plants to be able to see to the edge. I was rewarded by the discovery of part of a date which had been buried entirely.

I am pretty sure the letter that’s a bit hard to see here at the start is an r, so “-roleum Corp.” Petroleum, I guess, but I haven’t been able to figure out what petroleum business might also have installed sidewalks. The second line seems to be “-tion Div.” which I assume was Construction Division. The number definitely ends in 7, I can tell you that. Unfortunately the crucial number before that one is partly obliterated. What’s left suggests “2” to me.

The slab in context. Notice on the right how the surrounding sidewalk is wider.
