The King of Pop’s three children – Prince, 14, Paris, 13, and nine-year-old Blanket – along with their grandmother Katherine Jackson, signed some of the artwork by their dad, who died in 2009, aged 50.
Each drawing is said to reflect Jackson’s love of keys, chairs, and the number seven.
The music legend’s sister, La Toya, said the sketches are bound to “bring joy” to the children at the hospital.
She said: 'They're whimsical, they're magical and it's just joy and peace. I know that when you see this, and when the kids see it, it will bring some type of joy to them, and at the same time, I know it will bring some type of joy to my brother as well.'
The artwork is from the personal collection of artist Brett-Livingstone Strong, who was a close friend of Jackson’s.
