1907 – Blake & Bilger

Finally I have a decent example from this year, though it’s not in Oakland.

As they say, “You had one job.”

1920 – Aaron Dahlquist

5 October 2025

3141 San Pablo Avenue

Most Dahlquist stamps from this period include the month. Maybe he was in a hurry and didn’t add that part here.

1909 – Esterly Con. Co.

3 October 2025

2231 Tenth Street, Berkeley

There are two stamps here, both with the same barely readable date.

1906 – Contra Costa Construction Co.

2321 Ninth Street, Berkeley

My example from Oakland is pretty poor; this one is pretty fine.

This is as good an impression as you’ll ever get. The stretch of concrete here, some 120 years old, is worthy of “heritage sidewalk” designation.
