2804 Oliver Street
The first mark establishes the date. The second is on the other edge of the job and includes the name Moniz, presumably Arthur Moniz.

16 June 2015
2804 Oliver Street
I know the date because this one appears along with a dated mark by J. Widell.
1940 – J. Widell

No clue why J. Widell made that little gesture on the final zero.

13th Street at Harrison Street
Last year I found my first current-year mark in January. Usually it takes at least half the year, like it did this year.
1956 – Hayward Concrete Construction Co.

8654 International Boulevard
Out in Deep East, parts of E. 14th Street didn’t get made over. This is a new maker for me, in a part of town where I didn’t expect any maker’s marks at all.
1947 – F. Lopes

8628 Olive Street
Several years after his record of stamps gives out, Frank Lopes made this careful hand-drawn signature.
1937 – T. A. Ryan
11 June 2015
1712 86th Avenue
T. A. Ryan went through a lot of changes in 1937, using three different stamps over the course of the year. But on this day he just signed his work by hand.
