Michael Jackson's three children have made a rare public appearance to donate some of their father's artwork to a children's hospital in Los Angeles.

Prince, 14, Paris, 13 and Prince Michael II, 9, attended a special ceremony to hand over ten pieces of art created and signed by Jackson.

The sketches included one of Mickey Mouse, a throne and a drawing of Jackson's icon Peter Pan. There was one of his famous moonwalk.

Jackson's mother, Katherine, joined the children as well as his sister, La Toya, who said the pieces would help lift the children's spirits.

"You look at this, it makes you happy. They're whimsical, they're magical and there's just joy and peace."

"I know that when you see this and the kids see it, it will bring some type of joy to them, and at the same time, I know it will bring joy to my brother as well."

"I know that Michael wouldn't want this art in a better place, than a hospital like this that will help children, and people everywhere," she said.

"I'm so proud that these pieces are here to help those who need it."

The artwork was donated by Brett Livingstone-Strong, an artist and friend of the singer who died in 2009.

During the private ceremony, Jackson's children sat next to their grandmother and at times took turns holding her hand.

They added their own signatures underneath their father's on some of the pieces.

The art will eventually be placed at locations throughout the hospital.
