Sunset Blvd opened to the public on May 14, 1904, allowing the lucky few Angelenos who owned one of those new-fangled horseless carriages to go for a drive. This photo was taken that day looking west at the intersection of Sunset and Glendale Blvd (then known as Lake Shore Ave) in Echo Park. It looks like the single driver on the left is going so slowly that the dog is easily able to keep up with him.
