723 61st Street
Unlike the other 1931 Lovisone mark I have, this one’s date is way out of whack.

6319 Idaho Street
F. A. Mero has two marks here, the other one on the corresponding block of Baker Street.

6312 Herzog Street
A new maker for me, Kaus Bros. Allendale Avenue is the heart of the Allendale neighborhood in East Oakland, just downhill from the Laurel.

6250 Baker Street
I have an Estey mark already documented, but this is a much better example. Baker Street has about a dozen of these, so that’s where to go to see them. It’s a nice street in the Golden Gate district.

6172 Baker Street
I have a 1912 mark from Jepsen Bros., but this one has the date upside-down.

1042 63rd Street
Here’s another example of the mysterious mark I found on Alcatraz earlier this year. Now it’s revealed as a unique crescent design, but I couldn’t decipher the name until I found “Robt H” Hahn in the directory. He was listed that year as living at 3043 Grove Street (now MLK Way).
It appears that the R and the N are reversed. Perhaps a better example will turn up in Berkeley.
