Here’s a wonderful photo I found on EBay. I’ve seen many vintage postcards of downtown, but this one is new to me. Because it’s an extended exposure, there are no people, just lights. Note what appears to be some sort of vendor’s wagon or pushcart in the lower left corner. It’s hard to tell, but the Mason Opera House may be on the right side of the street, depending on when the photo was taken. The old LAPD Central Station would have been up to the right on 1st Street.
