For one, the emblem wasn’t always a signal of unity. In fact, the poster is broken up into sections, covering those that represented the British colonies (what up, "Don’t Tread On Me"?), some outliers from early fortified forts and sovereign states (colors!?!), and what seems like a fresh iteration every time a new state was integrated. (So. Many. Stars.)
