He had mad complicated styles and his lines could go on and on and on beyond the break of dawn. He was an MC, but to him M.C. meant Maurits Cornelis. The world, however, knew him by his initial-driven moniker, MC Escher , the innovative Dutch graphic artist who moved the art crowd with his math-inspired creations celebrated for their “impossible reality.” Although he was not from Harlem, Escher did attended the Haarlem School of Architecture and Decorative Arts in the Netherlands, so you could say he had swag like a Haarlem ninja (and always knew the day’s math).
