This happened two years ago but I only just found out.
Quentin Fiore was an American graphic designer best-known for The Medium is the Massage: An Inventory of Effects (1967) which he made with Marshall McLuhan, being a rumination on the adagium the medium is the message.

His designs include the I ❤ NY logo, the psychedelic Bob Dylan poster, and the logos for DC Comics and Brooklyn Brewery.
