Champions League winners Barcelona have signed a shirt deal with international children's welfare body Unicef.
Ronaldinho and co will wear the new shirt from next Tuesday
Barca president Joan Laporta announced the historic deal in Paris on Wednesday - Unicef's will be the first name to appear on front of the club's shirt.
"It's an historic agreement which shows the world our club is more than just a club," said Laporta, who was re-elected as Barcelona president in August.
"It's an initiative with soul. Barca can help the children of the world."
He added: "It's an historic moment as it is a prestigious logo and not just a publicity brand.
"It's an honour to wear the Unicef logo because it's an agreement without precedent for Unicef as well."
Founded in 1899, Barcelona have always resisted the temptation to have a paying shirt sponsor, although the team has advertised Catalan station TV3 on the left sleeve since 2005.
