Gustavo Cabral (born July 20, 1963), better known as Ciruelo ('plum tree'), is an Argentine fantasy artist,[1][2] whose work focuses especially on dragons.

At age 13 Cabral enrolled in Instituto Fernando Fader, an art school, where he began his formal studies.

He started working as illustrator at age 18 for a graphic advertising company, and soon after began doing comic covers.

In 1987 he moved to Barcelona, Spain where he drew fantasy books' covers and inside drawings for Timun Mas, a publisher that specializes in the genre.

[3] The art for Fuego gris was also used in Luis Alberto Spinetta's album of the same name, which was also the original soundtrack for the film.
