Did you know that the Arsenal changing room has no sharp square corners? AV believes that square corners are unlucky. Therefore when the new stadium was being built, he requested that the changing rooms have rounded corners. "It's interesting to note (though), that the visitors changing room corners are square." All we can say is, the Arsenal F.C. Home Changing Room Sign is definitely the perfect sign for your bathroom (with or without rounded corners). Put the metal sign on the door, and it becomes your personal space, branded a la the Gunners.
