Each of the some 6000 Chevy dealers got one of these posters. This one was shot by Warren Winstanley at the GM proving grounds not far from Detroit. The new rear styling was the big news in '61. The car had yet to be introduced and was a running prototype. Chevrolet was always very concerned about the security of new products and would let us photograph the car but only on the proving ground. They have so many roads there that finding a location was limited only to the places where we wouldn't get in the way of all the other activity. Shooting there required lots of planning and we couldn't go anywhere but our designated location. GM supplied a driver and other security personnel to make sure we didn't get into trouble.
