In 2004, on a bike ride through Kutztown, Pennsylvania, Scott and Angela Garner came across their dream home: a brick-built Victorian house with shutters on the windows and a wide porch at the front.
Inside was something completely unexpected. On the wall of a small downstairs room was a five-inch drawing just above the light switch. It was Radiant Baby, one of the most recognisable images of the wildly successful 1980s pop artist and activist Keith Haring, drawn in gold on a vibrant blue background in his childhood bedroom.
