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.
