The National Gallery of Art has been a little slow in producing tee-shirts that advertise its blockbuster shows.

Only this year did the museum overcome this reluctance and sell tee-shirts for the exhibition “Canaletto and His Rivals” and “Gauguin: Maker of Myth.”

At a press preview Tuesday, the museum unveiled the Warhol shirt. It is based on a design by Warhol for a Velvet Underground & Nico album cover.

The black shirt has Warhol’s signature underneath a huge banana.
