Friends, do me a favor and walk around the block wherever you live. Do you see any contractor stamps in the concrete sidewalk or driveways? How many?

I’m wondering if #Oakland has more of these than anywhere else, or if it’s just my proximity bias.

Since the start of the pandemic, @laureolaLaura Serra and I have been taking (almost) daily walks, sometimes seeking a new East Bay street so I can shoot more stamps. There are now over 1,000 photos in the album.

Overhead photo of a sidewalk corner. A hand pulls back some grass to reveal a mark stamped in the concrete: “THE OAKLAND PAVING CO”. The Ns are mirrored.

Another concrete stamp, this one in a shield shape.

Another concrete stamp, “Chas. Comers & Sons / General Cement Contractors”. Below the mark is a diamond shaped mark reading, “UNION MADE 149 LOCAL #594”
