While bumper stickers are everywhere, they’re also one of those things in life that are easily overlooked. After all, we’ve seen hundreds of them while sitting at red lights or crossing the country on road trips. They can say almost anything: support politicians, share pithy wisdom, or show off stick figure family trees.
