worked largely from photos. He and Warhol were not exactly close friends but nonetheless they had a bond, as can be seen in their personal style.The next few artists had little really in common with Andy Warhol both stylistically and personally. They did however frequent the Factory, which makes them worthwhile to mention. It is not beyond speculation that the mere socializing at Warhol's personal studio influenced them in some form or another. Richard Serra had a very simple and very unique form of sculpture.

They completely belied their weight; they appeared to be very light and easy to balance. Part of what made his pieces so interesting is that they easily could have killed a man if they were to be somehow knocked over.
