I was not aware of this:
The only piece of art on the moon (depending, we suppose, on one’s definition of art) is a 3″-tall aluminum sculpture titled “Fallen Astronaut.†It was created by Belgian artist Paul Van Hoeydonck and installed by Apollo 15 astronaut David Scott, along with a plaque bearing the names of the 14 astronauts and cosmonauts who died in the service of space exploration.
