Participants so far include (among others) Michael Mabry, Michael Cronan, Peter Kuper, whose work appears regularly in Time and Mad, and design legend Milton Glaser, whose ‘I (Heart) NY’ is arguably the most referenced design
in American popular culture.”
“Copyright-free” means you can use this art for anything, including adding your own information to it and even printing it commercially.
