Kaiser Hospital, Howe Street near Macarthur Boulevard
McGuire Hester is a giant contractor that’s working on the new Kaiser construction. Unfortunately they didn’t date their marks, or this would be a 2008. But since posting this I’ve found one from 2004.

Bilger was the owner of the Rockridge Shopping Center quarry; Blake was one of his partners. Blake & Bilger stamps are not rare, but they’re usually very hard to read. Two others are on 49th Street at Desmond and the corner of College and Hudson. I have seen Blake & Bilger marks in Berkeley with large double numerals in the center field (from 1907 and 1910), but I have yet to find a dated one in Oakland.
In front of Tech High, Broadway and 45th Street
Bennett did the sidewalks on this whole block, both sides of Broadway. The high school was built in (I think) 1915.

I’ve seen only two of these; the first is a partial print on College Avenue at Taft.
Armanino Court
This was actually a street patch, not a sidewalk, but a concrete mark from the East Bay Municipal Utility District was unusual enough that I let it count. Also, I love Armanino Court.
Across from 4225 Howe Street.
