Despite the discovery, New York City I, 1941 will still be displayed the wrong way up to avoid damaging it
A painting by abstract Dutch artist Piet Mondrian has been hanging upside down in various museums since it was first put on display 75 years ago, an art historian has found, but warned it could disintegrate if it was hung the right side up now.
The picture, a complex interlacing lattice of red, yellow, black and blue adhesives tapes titled New York City I, 1941, was first put on display at MoMA in 1945 but has hung at the art collection of the German federal state of North Rhine-Westphalia in Düsseldorf since 1980.
