Sketches by Michael Jackson as well as a signed portrait of the entertainer will decorate the walls of Children's Hospital Los Angeles.

Jackson's three children - Prince, Paris and Blanket - were on hand Monday to unveil the donated artwork. They include a dozen sketches drawn and signed by Jackson and a photographed portrait of him.

The works depicting Mickey Mouse, furniture and other objects were donated by Brett Livingstone-Strong, an artist and friend of Jackson's.

Former "Entertainment Tonight" host Mary Hart, a hospital trustee, arranged the donation. She says the sketches show a different side of Jackson.

The singer's sister, La Toya Jackson, says she believes the art will bring joy to children at the hospital.
