John Kenn Mortensen

John Kenn Mortensen (Don Kenn) is A Danish artist who draws monsters on Post-It notes. We read in demilked.com:

He writes and directs television shows for kids, but during his free time he pays tribute to the darker, spookier side of childhood filled with monsters and ghosts. Ugly, terrifying and bone-chilling monsters creep out of the darkest childhood nightmares and right into Kenn’s sticky notes. That’s right – the artist draws his highly imaginative little scenarios, where kids meet ghastly monsters, entirely on yellow post-its.
