No amount of digging unearthed any more information about this photo other than it was taken in Irvine, CA in the late 1920s. Irvine is 40 miles south of downtown Los Angeles and as far as I can tell, it didn’t start being developed until the 1960s. So if this photo was taken in Irvine, it was more likely Irvine Ranch, which was a 60,000-acre lima bean farm. So what this caravan of cars was doing out there in the middle of nowhere is a anyone’s guess.
