Great thread, Carey. I am a long time Delta Lines fan. Some one mentioned that it would be amazing to see what Frank would do with a laser cutter, but Frank was a master at creating illusions with less. He was a theatrical designer. I'm not sure he would have needed or wanted more technology.
May I ask about the painted backdrop in your photos? Is that original Delta Lines? It has the forced perspective and style of painting that I would associate with Ellison and the period.
