A cheeky football banner designed by Irish fans that made headlines across the world has been sold at auction for almost €16,000.

Irish football fans first unveiled the "Angela Merkel Thinks We're At Work" tricolour at Dublin airport earlier this month while en route to Poland for Euro 2012.

The banner went viral on social networking sites before reaching the front page of two Irish national newspapers, the BBC website, US television and even on to Germany's best-selling newspaper, Bild.

The six University of Limerick graduates who uploaded the original picture auctioned the banner on RTÉ radio this morning with all funds raised going to good causes.

The tricolour was won by Antrim-based Glendun Group and Iris R&D, who submitted a joint bid totalling €15,800.

Well-known Dublin pub Copper Face Jacks, who submitted a losing bid, donated a further €5,000.

The funds are to be split between the Children's Medical and Research Foundation in Dublin and the Oscar Appeal, set up to help provide treatment for Oscar Knox, a three-year-old Belfast boy with neuroblastoma, a cancer that develops from nerve tissue.
