LOS ANGELES, USA - Late actor Dennis Hopper owned a remarkable collection of art dating back to the 60s from Andy Warhol s Mao Zedong and Conner s Picnic on the Grass .

The collection, which spans more than 300 paintings started from a conversation Hopper had with actor Vincent Price, who influenced and persuaded him to put his money into art.

Dennis Hopper was an avid collector, and also a photographer and painter outside of his acting.

In one incident in the early 1970s, Hopper had a fit of fear when Warhol s Mao painting frightened him one night. He shot it twice and it became part of the painting s history.

Hopper s posters, including Apolocalypse Now, and handwritten notes will go on sale.
