New art by the elusive street artist Banksy, honoring health workers, has been revealed at a British hospital. The framed picture, titled “Game Changer,” portrays a young boy sitting on the floor playing with a nurse superhero toy.

Batman and Spiderman action figure toys lie in a wastepaper basket next to the boy. The nurse figure, complete with a cape and a confront cover, wears an apron including a red cross — the only a spot of color within the black-and-white work. The piece has been set on display in a passage at Southampton General Hospital in southern England on Wednesday.

The artist has left a note for hospital workers, saying: “Thanks for all you’re doing. I hope this brightens the place up a bit, even if (it’s) only dark and white.”

The artwork will be sold afterward to raise cash for national health charities.
