From the handle placement and orientation plus the state of the right hand door, my guess is that they are hinged vertical panels that slide sideways and bend at the side to travel back into the bay. Sort of like the modern vertical garage doors mounted sideways.

Do the garage doors slide or fold? I think they slide. Any ideas?

I imagine got a good workout in the winter months. Looks like a great place to hang out and have a game of checkers and catch up on the local news.

The only thing missing is the rubber hose to ring the bell to indicate that someone is waiting at the pumps. In reality it is probably hidden by the bushes and the car.

On March 18 Roy Stryker had written to Vachon that he was trying to get new tires for his old car. Even being a government employee was apparently not a free ticket during war rationing. I wonder if Vachon had eyed the tires in this station, but the approval wasn't expected until near the end of April.

I notice John Vachon called this a service station, not a gas station. I remember the days when you pulled your car up next to a gas pump and told the attendant who came out to greet you how much you wanted of which grade. While you sat in your car or did whatever you needed to do the attendant put gas in your tank, cleaned your front and rear windshields, checked your oil and told you the results, maybe put water in your radiator or windshield wiper tank, and checked the pressure in all four of your tires. As a norm attendants were not given tips; it was just part of going to a service station.
