This is in the pavement in front of Ralph Bunche High School. I hope it lasts a long time.

1825 Linden Street
This shows that Rosas Brothers did indeed have a stamp made for the year 2011; until now all my examples were hand-altered from a different year. The blocks around here have dozens more.

Union Street at 21st Street
There are several of these around the big East Bay MUD center. I recorded another EBMUD mark four years ago with a different logo and no date. Glad to have this one now.

4415 Park Boulevard
There are lots of marks along lower Park Boulevard, east of 580, but very few on upper Park.

1960 Mandela Parkway
I believe this is the only concrete stamp on all of Mandela. It sits next to the American Steel building, and somehow it escaped the repaving after the 1989 earthquake. I think this group must have been the developers of the site. Wikipedia tells me that the firm was the developer of the Cypress Structure, although that contract started in 1956.
