Here's a detail from another image in the set. One of the "X"s is in front of the large palm in the center. Down the street is the Groch Engineering Co (oil and mining engineering) at 1212 W 2nd Street.

Having said that, I liked BillinGlendaleCA's version better . It also reminded me of the end of "It's a Mad, Mad, Mad, Mad World", which I rewatched a couple of weeks ago (I know that was a big "W").

Perhaps it's a "Do Not Enter" sign on a one way street.
