Thomas Kinkade, who was best known for his paintings of idyllic landscapes, churches and cottages, died at his home in the Los Gatos area of San Francisco Bay, California on Friday.
Kinkade's sentimental works were said to fetch around $100m (£63m) a year in the US but were not popular with the art establishment.
He died of natural causes.
Kinkade's paintings generally depict tranquil scenes, such as country garderns and churches, while many featured images from passages of the Bible.
I love his paintings, I've got two small prints of his in my living room.
Very sad. RIP
