This is a long shot…
My enigmatic high school ceramics/physics teacher (he was a mad scientist type) had a very strange poster. We asked about it constantly, but he would only flash his trademark enigmatic smile and shake his head.
It had George Washington, like on a dollar bill. Under one of his eyebrows was a rainbow. Across the bottom it said something along the lines of “It’s a tough job” in the font they use on money.
Please, has anyone ever seen this? What could this possibly mean?
