Portrait painting by Andrew Wyeth, LeadArt oil painting just do reproduction of them in museum quality on linen canvas:

Andrew Newell Wyeth (July 12, 1917 – January 16, 2009) was a visual artist, primarily a realist painter, working predominantly in a regionalist style. He was one of the best-known U.S. artists of the middle 20th century, and was sometimes referred to as the "Painter of the People," due to his work's popularity with the American public.
In his art, Wyeth's favorite subjects were the land and people around him, both in his hometown of Chadds Ford, Pennsylvania, and at his summer home in Cushing, Maine.
One of the most well-known images in 20th-century American art is his painting, Christina's World, currently in the collection of the Museum of Modern Art in New York City.
