1931 – Poblitz

24 November 2010

1931

5268 Golden Gate Avenue

This mark clearly displays the bottom row, making it obvious that AND-1661 was a phone number. It’s odd that Poblitz didn’t consider the last four digits permanent.

1928 – Geo. Thomas

23 November 2010

1928

601 23rd Street

Unlike the Geo. Thomas marks from the 1930s, this one does not include the phone number.

1917 – The Oakland Paving Co.

1917

2816 Martin Luther King Jr. Way

1910 – The Oakland Paving Co.

21 November 2010

1910

5950 Romany Road

Even before I started this blog, the pair of marks at the corner of Cross and Romany Roads stood out to me. I imagine that the workers of The Oakland Paving Co. were eager to show off their work in the then-new subdivisions of Broadway Terrace. Consequently this mark is deep and precise, ready for another century of service.

1958 – A. G. Moniz

1958

516 25th Street

I’m guessing that this is the Moniz found on the Andrade & Moniz mark. Very few concrete workers are confident enough to draw a mark of this quality without using a stamp.

1947 – A. Sposeto

19 November 2010

1948

2300 block Valley Street

Angelo C. Sposeto also used an undated barrel-shaped mark, otherwise I wouldn’t know who this is.

Just the other day, I saw sidewalk barriers put up by Sposeto contractors on the Cal campus. Could they be the successor to Angelo’s company?

1937 – M. Cvetich

17 November 2010

1937

515 Sycamore Street

This matches the 1935 Cvetich mark, but not the 1936 mark.
