I am hoping the Alhambra McMM location was in
e_r's photo because of the very noir 1930 holdup story.
The 1947 Baldwin Park directory has:
McDaniel's Market R A Faiman mgr 108 E Ramona BP
but no Shaw's beauty salon is listed.
A 1931 Sanborn map of BP:
...compared with the ad found by
ProphetM and
HossC suggests the streets were renamed between 1931 and 1934. But there is no structure at what would have been the 100 block of E. Ramona in 1931.
The street alignment is more or less the same today:
...although the numbering is different.
