Autistic Artist Drew the New York City Skyline From Memory After a 20-Minute Helicopter Ride

This astonishing 18ft drawing of the world’s most famous skyline was created by autistic artist Stephen Wiltshire after he spent just 20 minutes in a helicopter gazing at the panorama. The unbelievably intricate picture was drawn at Brooklyn’s prestigious Pratt Institute from Stephen’s memory, with details of every building sketched in to scale. Landmarks, including the Empire State Building and the Chrysler Building, could be seen towering above smaller buildings after just three days into his spellbinding creation. Diagnosed with autism at an early age, Stephen's talent for drawing emerged as a way of expressing himself. Today, his drawings sell from anywhere from $900 to $19,000 and his net worth is estimated to be $11 million.
