A painting bought at a garage sale in Minnesota is a previously unknown portrait by Dutch artist Vincent Van Gogh, according to a newly published expert analysis.

A New York-based art research firm believes a painting bought in 2016 for about $50 at a Minnetonka garage sale is a Van Gogh masterpiece entitled "Elimar."

A red hair — the color of van Gogh’s locks — was found embedded in the paint, which was proven to be from early 19th century France.
