"The art collection of The Andy Warhol Museum at Pennsylvania includes over 8,000 works in all media-paintings, drawings, prints, photographs, sculpture, and installation. The collection provides an in-depth view of every period of the artist's creative life, from the 1940s through the 1980s." You can visit their site
