I saw my Billboard from my car and it was F'in awesome
Katz comes into our office, excited. He'd scored a deal to get billboard space on 40 digital Billboards for free (or close to free). They needed the designs for two billboards in an hour. I delivered. The joys of Gill Sans and not much else. I imagine given more then an hour I could have done much more, but I work with the time given.
