Forget those posters with the dangling kitten, urging you to "hang in there." And that motivational poster trend that swept the internet a couple of years ago? Passe. Rob Kelly 's classic monster public service announcements are where it's at!

Kelly manipulates old photos to create his PSAs, pairing stars from cult classics and golden age shockers with hilariously fitting advice like "Bela Lugosi Is Concerned About Your Credit Card Debt" and "Lionel Atwill Wants You to Straighten Up and Fly Right." I can appreciate any artist who makes a triptych of PSA posters based on Wes Craven's Swamp Thing. Make sure you visit Rob Kelly's actual site to see them all; I've only included about half of them here.
