Here is an extremely worn Department of Public Works stamp from the east side of North Clemens Avenue between Vine and Fernwood. It caught my eye because the date appears to be from the teens, making it among the oldest DPW stamps I have catalogued. That penultimate digit sure looks like a one, anyway, though it’s strange that I don’t see a spot for a month. As far as I have seen, they used a month stamp through at least 1924. It might be worn away, but it’s less likely given that the year is nearly centered.

The last digit is harder to read. I took it to be a nine when I saw it in person, though on closer look at the photograph it might actually be an eight.
