Driver's Licenses Around the World

We were stopping for gas at Kroger after doing the monthly pilgrimage to Home Depot for their Kid's Workshop when H asked me what my driver's license look like. I showed it to him, but I also recalled this guy, Glenn, I worked with at Bloomberg. He was originally from the London office. I saw his "driver's license" once. It was a plain, boring sheet of cheap printer paper, some 15 or 20 years old. Completely unreadable. But that was what passed as a driver's license. Kind of crazy. I guess they probably didn't use that for airport security?
