Here's another example of how "modern art" can hardly be called art.

This apparently famous artwork by a well-renowned modern artist has been hanging up upside down in a museum for literal decades and no one could tell.

Yeah, these paintings from Piet Mondrian are usually just these lines, boxes, and colors in no real discernible purpose.

It literally makes no difference how you look at it. It's just boxes.

The painting, called "New York City I," features Mondrian's classic primary color palette and striking geometric lines. The Dutch artist made a series of "New York City" paintings in 1941 and 1942 after relocating to the city from Europe.

"New York City I" has long been shown with the thickest cluster of lines at the bottom of the frame, according to an exhibition catalog from the Kunstsammlung Nordrhein-Westfalen, the German gallery that acquired the painting in 1980. The museum is hosting an exhibition dedicated to Mondrian's work.

But a photo of the work in Mondrian's studio shows the painting with the reverse orientation — suggesting this might be how the artist wanted it to be shown.

I'm sorry, maybe I don't "get" art, but if you can't tell what side is up or down what's the point?

It's just squares.

I don't get it.

It might be impossible to ever know the correct orientation for sure, says the museum the catalog. The painter died in 1944.

Still, "if we go along with the experiment and rotate New York City 1 by 180 degrees, we find that the picture still 'works,'" claims the museum in the catalog. "In fact, it functions extremely well: the composition gains in intensity and plasticity."

Oh, it still "works"? What exactly does it work at doing?

They aren't even going to fix it. It doesn't matter if it's upside down or not.

Modern art is just a joke.
