Is that actually a vintage photo, or just made to look like one? Pretty clear, and funny!
I vote that it's not real because for all the wall you see reflected on the car, you don't see any of the sign.
If it isn't real, then someone went through INCREDIBLE pains to replicate the clothing for a fake shot.
The overalls on the guy on the right are of a style that no one makes anymore.
The light bulb in the garage is not a bulb that anyone makes anymore. That's a detail one one would pick up when faking a shot. They would just delete any modern light fixtures.
There are two cars reflected in the door of the car, both are vintage cars.
Lastly, the cobblestone driveway would most likely be paved over now...and it's a detail no one would pick up to fake a shot.
