1988 – M. Andrade & Son

29 March 2018

18 Monticello Avenue, Piedmont

This is way later than my next-youngest mark, from 1974.

1975 – Geo. Jardin

27 March 2018

317 Ramona Avenue, Piedmont

Stamps with dates from the 1970s are pretty rare, but George Jardin stuck it out through the whole decade and up to 1988.

1944 – Ed Doty (straight mark)

23 March 2018

143 Waldo Way, Piedmont

This straight mark was used by Ed Doty even after he adopted the “Master Concrete” stamp in 1937. With this example, I’ve documented each year from then up to 1944. If I find a 1945 example, that will complete the set.

1943 – Moniz & Moniz

22 March 2018

169 Ronada Avenue, Piedmont

Now I have this scroll documented from 1943, 1951, 1952 and 1957.

2008 – All Seasons Construction

21 March 2018

75 Arroyo Avenue, Piedmont

1974 – Geo. Jardin

19 March 2018

24 York Avenue, Piedmont

1959 – Larry Frye

18 March 2018

6 Wildwood Avenue, Piedmont

There aren’t a lot of Larry Frye marks out there, so I was happy to find a new date for him.
