Apparently, a famous painting by abstract artist, Piet Mondrian has been hanging upside down for the past 75 years. The Dutch artist created the picture, by putting strips of black, blue, red, and yellow adhesive tape on canvas in 1941.

The artwork called New York City 1 is currently part of the collection of the German state of North Rhine-Westaphalia in Dusseldorf.

An expert has recently concluded that the artwork, which has hung in galleries and museums around the world since 1945, is being displayed upside down.

Now to be fair, they can’t be absolutely certain, since the famous artist died in 1944.

But this guess is based on a similar adhesive tape painting that Mondrian constructed that is apparently hanging the other way.

Of course, it is entirely possible this other painting is upside down, and New York City 1 is being displayed properly.

Whatever the case, New York City 1 will not be hung the other way because of fears this could destroy the abstract art constructed of now dried-up adhesive tape.
