This reminds me, I used to work in this office that was mostly work and warehouse space for a hat importer and customizer. It was in an industrial section and there was a line of rail for some other company.
One day a box car with a giant picture of Milhouse showed up and text that said, “Everything is coming up Milhouse.” I took a film photograph of it, which I am sure I have somewhere still. A really cool piece of train art IMO.
