Fourteen-year-old Prince, 13-year-old Paris and nine-year-old Blanket Jackson donated 10 pictures, all signed by the King of Pop himself, to the Children's Hospital Los Angeles - which will display them to cheer up patients.
The kids were chaperoned by their grandmother, Katherine Jackson, and aunt, LaToya Jackson.
The late singer sketched a series of throne-style chairs specifically for his kids: “Paris’ Magic Pixie Chair,” “Prince’s Empire Chair”, and “George Washington’s Good Morning Blanket Chair”.
Each child wrote a heartfelt message to their father on their drawing before giving them away.
“My father’s art and music will always make everyone happy. I love you daddy,” wrote Blanket Jackson, who donned white socks, dark loafers and wore his hair in a ponytail - reminiscent of his dad's signature style.
“May the very special memory of my beautiful, loving father be always in our world forever,” wrote Paris. “Especially through his wonderful and magical art, bringing endless happiness to children everywhere.”
The other pieces featured Mickey Mouse, Peter Pan, keys with faces, and shoes.
