“Our favorite climbing gym, Mission Cliffs in San Francisco, recently asked us to redesign its identity. Housed in a former foundry, the gym has an urban, industrial feel: concrete floors, steel I-beams and a massive crane hook. The sketchbook page demonstrates that Mark works at a small scale: most of his trademark concept sketches are in the three-eighths-inch range. After enlarging the sketch, he tests the idea by inking it with a Rapidograph pen prior to building the art in Illustrator. The second and final inking of the MC monogram is around five-and-three-quarters inches wide.”
