Vintage AAA Materials?

[GowerGulch42]

Many of us know about the various AAA (and other) road signs scattered through the DV backcountry, and some written and photographic accounts of AAA excursions from the 1920s and 30s survive. Anyone here familiar with archival AAA or automotive materials that may give more details about routes through the park or travel guides from the 1930s and 20s before many of the roads we now use were made? For example, there was a route that went up the N. Fork of Lemoigne to Cottonwood Springs. The road trace is long gone but there are automotive artifacts in the area that are known to backcountry explorers. Trying to tread carefully here about what I say and what I want to know… 

I think my question is clear enough. If I find anything on my own I'll share it.

No luck yet, but this is interesting. Look how different the naming is, and the complete lack of detail in the landscape:

VERY old map of DV

Here's a collection of 17 photographs from the Automobile Club of Southern California, ca. 1926. Cant figure out where this first one is, or any others to be frank.
