Prosecutors say a controversial painting by late artist Chun Kyung-ja is an authentic work, despite consistent claims by the artist that it was a fake.

The painting, “Beautiful Woman,”  has been at the center of a forgery debate since 1991. 

The Seoul Central District Prosecutors’ Office on Monday dismissed the charges brought by Kim Jeong-hee, Chun’s daughter, against five officials at the National Museum of Modern and Contemporary Art(MMCA), including Director Bartomeu Mari Ribas, who owns the work.

Kim argued that the five people claimed the painting is authentic although it is a fake.

The prosecution concluded that the painting is authentic after thoroughly examining the work using state-of-the-art techniques, including infrared light, computerized imaging analysis and DNA analysis.

It said that Chun’s unique characteristics, seen in her other works, were consistently found in the painting.
