There are a lot of billboards with large pictures of food on them that will make you hungry, but while creating this billboard ad for Greggs, artist Hammo probably worked up quite an appetite himself.
The #FreshBillboard started out as a big blank space, which was painted live on Old Street in London. As well as being just purely awesome to watch Hammo at work, the #FreshBillboard was tied to a social campaign that challenged people passing by to guess what Greggs sandwich would be painted next. The live painting of the billboard went on for the entire week and those who participated in guessing the next sandwich to be painted got the chance to win a free lunch from Greggs.
