I would be the first to do this myself, but honestly, if the end of the world was upon us and they were saving valuable pieces of art, I just don't think pinball would be included. It's the cold hard truth.
But of course, assuming we live in a fairytale land where everyone cares as much about pinball as we do, I'd want us to save Twilight Zone. I know a lot of people are going to say that too, but there's good reason. Twilght Zone was built to be the most excessive pinball machine ever. To this day, it still is. It has everything a great pinball machine should have: ramps, magnets, a mini playfield, toys (gum ball machine), cross playfield shots, great music, great theme, and the most classic of all wizard modes, the "Pat Lawlor style, everything is lit one by one on the dmd, now it's time for mega crazy multi ball".
So yeah TZ for sure.
