Interesting, I’ve never seen that before. Certainly painted from life, as nobody would have come up with that exact scene form their imagination.
I have always wondered how many people have modeled his most well-known painting, “Nighthawks” over the years on their layouts? https://en.wikipedia.org/wiki/Nighthawks
John Armstrong, for one, modeled this scene exactly. I think I was one of the first to spot it and identify it after he installed it. Don't know if it survived the dismantling of the CS after his passing.
