I assume that this whole subdivision, east of Skyline in the highest hills, was laid out and paved this year, but Gallagher & Burk left just the one mark.
This is a street corner with a 1940 WPA stamp on it, plus this signature. It’s the first example I’ve found of someone putting his name (intials, anyway) on a WPA project. (I tried to get both parts on one shot, hence the odd angle.)
This is not only a better strike, but an earlier strike from this founding year of Carlos Valenzuela’s career. Another thing about this driveway site is that he put his mark on the corners of the driveway as well as at the mouth.
