My friend Melissa must have known that SimTower was a favorite computer game during my younger years. A big, huge thanks to her for pointing out these great cross section illustrations featured on a website that I can’t believe that I had not heard of before: Retronaut!
My favorites are the theater and the department store. Tiny costume shop! Tiny automat!
It is greatly worth your time to visit the website proper and see these images in their expanded glory. Go, go!
