MARCOS B is a self-taught Galician artist whose passions are mystery, adventures, and fantasy. His works are a showcase of two very different styles: a more realistic and detailed style, in works of a more grown-up nature, and a simpler, freer style for his humor. Though he has never stopped drawing and creating stories, it was not until 2013, with the publication of his first graphic novel, The Adventures of M&M, The Old House on the Cliff, that he started doing it professionally. Since then, he has collaborated with magazines such as ¡HEY! and Exégesis, and has worked with publishing houses such as Baía, Edinumen, and Tebeox. Currently he combines his work as an illustrator with developing his own original projects, which include the new adventures of M&M.
