R.U.R. Robot

Looks like the tin man’s wants to pop Dorothy because Toto peed on his leg. Fortunately he’s been restrained. He wasn’t a nice guy in those days.

Actually it’s a promo for a 1928 production of the 1921 play R.U.R. [“Rossum’s Universal Robots”] that introduced the word “robot” to the world. Ever since then the control panel has always been in the front.
