Pioneering US artist's work back in Beijing after his passing

Recalling his first exhibition in China a year earlier, US artist Robert Rauschenberg (1925-2008) said in a New York Times interview in 1986 that people from the National Art Museum of China - where his show was to open - were so excited at his idea that they kept providing him more exhibition space.

The additional costs of transportation and security put him under huge pressure.

The final display at the Beijing-based museum included 47 huge paintings and sculpture installations.
