Nelson Mandela has won the first round of a legal battle over the use of his name for fundraising purposes.
Some of Mandela's work is on display in Johannesburg
The former South African leader gained a court order against his former lawyer and a businessman, stopping them from selling artwork in his name.
Lawyer Ismail Ayob and businessman Ross Calder did not oppose the interdict.
Mr Mandela is to make a second court application demanding that Mr Ayob and Mr Calder account for funds already raised from the art sales.
Mr Mandela did not attend the hearing in the Johannesburg High Court on Tuesday.
"These artworks have been marketed and sold without any accounting to Mr Mandela," the former president's lawyer, Vincent Maleka, told the court.
Mr Maleka said there was "incontrovertible evidence that a number of galleries around the world are selling such artworks with the authority of Mr Calder."
The sale of artefacts supposedly signed by Mr Mandela - including lithograph prints, books and copies of the statesman's handprint - was originally promoted as a charity venture.
George Bizos, an advocate and long-time friend of Mr Mandela, has said that some $4m arising from the sale of Mandela artworks and memorabilia worldwide remained unaccounted for.
