The most expensive installation with a banana is the work of Italian artist Maurizio Cattelan titled "Comedian".

It consists of a banana taped to the wall with silver duct tape.

In 2019, at the Art Basel art fair in Miami Beach, the installation was sold for $120,000, and then for $150,000. Later, at a Sotheby's auction in New York in 2024, a copy of "Comedian" was sold for $120,000.

Ultimately, in the same year, another version of the work, also by Cattelan, reached a price of $6.24 million.

In short, "Comedian" is a banana taped to the wall that has become one of the most expensive works of contemporary art. The price it achieved sparked much controversy and discussion in the art world.
