A Dutch art dealer has discovered a painting by Rembrandt that hasn't been seen in about 400 years. The portrait of a well-dressed young man was presented this week as the first rare Rembrandt painting to surface since 1974. It will be on display at a museum in Amsterdam for one month. Art dealer Jan Six found the painting at a London auction and bought it for $185,000. In 2009, a Rembrandt painting sold for $33,000,000 dollars.
