Take Part In A Clue-Based Tube Game
Take Part In A Clue-Based #Tube Game - CBS Outdoor launch a clue-based brand-hunt tomorrow celebrating 150 years of #adverts on #LondonUnderground. The challenge, should you choose to accept it, is to work out the identity of 150 #brands that have advertised their products on the tube. Like their Look for Longer poster, it’s a fiendishly fun puzzle.
