I found a copy of the So. Cal National Old Trails Auto Guide, 1916, online. It can be read and downloaded for free.

Quite interesting. I first thought a page might be missing when I saw Kansas City at the east end of the index map but it seems the strip maps really do cover KC to LA (or LA to KC:-). The tributaries are interesting in their own right. Curious that the Lincoln Memorial Highway was considered a tributary in Colorado although the state had already been dropped by the LHA. I have scanned copies of the 1925 and 1932 guides that do include the whole route all the way to New York. Good find.
