The Prado, home to so many masterpieces now houses one more "The Wine of St. Martin's Day" by Pieter Breugel the Elder. The painting has been in the Prado's collection but was recently re-attributed. The New York Times has a nice interactive feature where you can mouse over the painting to zoom in for a closer look. Painters' Table recommends a visit to the Prado to see the work in person but the Times feature offers a nice preview and they published a related article you can read as well.
