Two former students are selling advertising space on their faces as a means of paying off university debts.Cambridge graduates Ed Moyse, 22, from Poole, Dorset, and friend Ross Harper, 21, from Blackheath, London, are painting a different company logo on to their faces for the next year.After 10 days they have made £3,500.Mr Moyse said: "It's something a bit different at a time when students feel let down by the education system and the hostile graduate job climate."He came up with the idea with Mr Harper, who studied neuroscience, after graduating in the summer as a scheme which would not require much investment.'No abuse'They sold their first face ads to friends and family members with businesses for £1 a day, with the cost gradually increasing throughout the year.But Mr Moyse, who studied economics, said this had only contributed about £20 to the total so far with the rest coming from unrelated companies, some of which have paid substantially more than the daily rate.The pair intend to travel around the country and post pictures of themselves on their website to raise their profile.Mr Moyse added: "It's taken off quite nicely. It has exceeded expectations, we always knew it had value and is novel and crazy."Just doing normal things can end up being quite funny."When we go out at night we quite often get hugs from people who have maybe drank one or two too many but so far we have not got any abuse."
