You are right, FFF-- and the phone pole would be running along 2nd street parallel to Main--the street to the right is called Norman Place.
If it weren't for the "25", which I hadn't noticed before, I might ask, what if the company had an identical building at 8613 W Pico in 1939, for which there is a listing in the '39 LACD... I only say this because of the typical Pico Blvd streetlamp still in front of that location...but then again, it doesn't seem to be in quite the right spot--and, as it turns out, the vintage SM street lamps (below) are very similar to those still standing on Pico. So a radical renovation in SM it was... excellent sleuthing, FFF.
