Hang out at this Vancouver bus stop and you might be started by what you see. McDonalds and ad agency, Cossette, have created a bus shelter billboard featuring a cup of coffee that periodically expels steam and uncovers a hidden message! What does it say? “Your free coffee is ready." So, let me get this straight. Not only is this ad super cool...it's telling me I can pick up some free coffee? I'm lovin' it!
