Actions Speak Louder Than Bumper Stickers

Outside the sprawling metropolis of New York the all-American way to express political beliefs is to stick a big fat sticker on the bumper of your car.

It's a peculiar tradition, documented for the first time in a new book edited by Olivia Greer and Aaron Rudenstine. They've collected some of the funniest political bumper stickers - left and right - and created a colourful book sprinkled with political facts that ground roadside chuckles in reality. You can buy the book on their website.
