I used to live around the corner from where Andy Warhol had his offices for Interview Magazine & I used to see him around the neighborhood all the time. The building had huge windows on one side, and there was a balcony inside that overlooked those windows.
One day I was walking past and glanced up and saw a lifesize cardboard cutout of Warhol on the balcony. I stopped and looked at it thinking, 'wow, that looks almost lifelike.' Then it moved.
Turned out it wasn't a cardboard cutout afterall. It was him and he looked almost lifelike.
