British heritage bakery, Greggs, launched its new range of sandwiches with experiential murals designed and painted by our artists over 5 consecutive mornings. Supported by a promo team over the course of the week, commuters were encouraged to tweet with the hashtag #FreshBillboard and guess which sandwich was being painted in return for daily prize giveaways and sandwich vouchers for the masses. The live painting was also filmed daily and broadcast on the Greggs’ website and social media platforms each evening, allowing viewers to see every piece of original art created and get involved.
