This stamp is on the curb cut leading from Jerome Street across Marshall, on the northwest corner of the intersection. The date is a little unclear but I believe it is 1981. I can find a record for Ayala’s Concrete and Excavating at OpenCorporates, according to which it was located on Bedford Road in Lansing. It was incorporated in 1979 and dissolved in 1992.

I took a photo for you diagonally across the intersection so you could get a glimpse of the Christmas lights on the mansion on Jerome I have mentioned before.
