Rafael Lopez uses his hands and imagination to create award-winning children's books and murals around the world. He has been awarded the Pura Belpr medal from the American Library Association two times, for Drum Dream Girl and Book Fiesta.

Born and raised in Mexico City to architect parents, Rafael grew up immersed in the rich visual heritage, vivid color, music, and surrealism of his native culture. He enjoys working hand in hand with children, librarians, and teachers to paint community-based murals in neighborhoods.

Rafael divides his time and collects ideas in his studios in colonial San Miguel de Allende, Mexico, and downtown San Diego, California, where he lives with his wife and son.
