Gustavo Cabral (born July 20, 1963 in Buenos Aires, Argentina), better known as Ciruelo, is an Argentine fantasy artist whose art typically focuses on dragons. He provided artwork for Magic: The Gathering, George Lucas' Chronicles of the Shadow War, and magazines such as Playboy and Heavy Metal.
At least four published books have been focused on his drawings: The Book of the Dragon, Ciruelo, Luz, the Art of Ciruelo, and Magia, the Ciruelo Sketchbook. He typically uses mainly acrylic and oil paints. Unlike most artists Ciruelo is actually color blind.
