Rubén Martínez is a Madrid based graphic designer and art director, heavily influenced by the tattoo and skate scenes. I really like his approach to typography. He manages to create type that’s simple and clear, yet full of character. His illustrations are great too, especially ‘Watch Out!’ which has a bit of an art nouveau quirkiness to it.
