#3: A Secret Passage
This next picture is from a comic book supervillain’s evil lair, and you cannot convince me otherwise. What other reason could a person possibly have for a giant hidden door into some kind of big industrial space?

Well, I suppose it’s possible that this is a business somewhere, and they are trying not to ruin the local aesthetic, but I personally prefer to believe in the supervillain theory. I also suddenly have a desperate need to become a supervillain so that I can have this door.
