I'm loving everyone's detective work so much, that i'm curious if anyone knows about this.
There was a place called Diana Ballroom in the late 1930's at 4067 W. Pico Blvd.
This is what i came up with from Google, i can't make out the top of the sign and it's hard to believe it would still be there.
The Trianon Ballroom at 2800 Firestone Blvd. was torn down as well just a few years ago.
All these old Ballrooms have disappeared =(
