answer: It was there on loan. It belongs to the Museum of Modern Art in New York City. See attached link.

It still is, it's just a shorter way to say it instead of the Museum of Modern Art.

The Museum of Modern Art (MoMA) is an art museum in Midtown Manhattan in New York City, on 53rd Street, between Fifth and Sixth Avenues. It has been important in developing and collecting modernist art, and is often identified as the most influential museum of modern art in the world. The museum's collection offers an overview of modern and contemporary art.
