One hundred-year-old artist Grandma Moses (1860-1961) painting at her farm in 1960. She was a renowned American folk artist. Having begun painting in earnest at the age of 78, she is often cited as an example of an individual successfully beginning a career in the arts at an advanced age. Her works have been shown and sold in the United States and abroad and have been marketed on greeting cards and other merchandise. Moses' paintings are among the collections of many museums.
