Lick a billboard

Chocolate manufacturer Thorntons is presenting the world's first edible billboard on March 29th. It will be up in Tottenham Court in London and weighs 285 kilos. Not sure exactly where it will be and what it will look like (hence the Artist's Impression I created) but I am sure if you follow the crowd, you will come across a large group of women licking a billboard and you know you have found it!!
