A driveway apron on the north side of Jerome between Ferguson and Custer caught my eye. It is relatively uncommon to have stamps at all on the driveway, but this one had four! The two pictured stamps are set diagonally on either corner, facing the sidewalk.
At first I was going to joke that they must have been especially proud of their work to stamp it twice, but then I realized the likely reason. There are actually two contiguous driveways here that share one big curb cut, as is common in the neighborhood. The double corner stamps are probably signaling “we did this side; the other side is some other contractor’s problem.” The other side has a single 1987 BWL stamp on it.
There are also upper and lower blocks making up each of the two sides. The DPW stamps are on the upper block, next to the sidewalk. The L & L stamp is on the lower block, next to the road.
