I thought you might like a little map of Hollywood published in Motion Picture Magazine in 1926. The magazine was read nationally and so much of this geography would not be familiar to its audience (though they would know the streets intimately from the location shoots in and around the area).
Interestingly enough, the map is drawn to emulate an older style, so this is doubly retro! Also, tongue-in-cheek because some of these locations are a bit (whistles) red hot! Which studio would you visit first if you found yourself in 1926? I’d head over to the DeMille Studio, methinks.
