'Worn out': New van Gogh drawing of old man discovered

A newly discovered Vincent van Gogh drawing that has been hidden in a private collection for more than a century went on display for the first time at an Amsterdam museum on Thursday. "Study for 'Worn Out'", which depicts an old man sitting in a chair, was sketched by van Gogh in November 1882 when he was just starting the career that would later produce masterpieces like "Sunflowers".
