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.
