So... every now and then the little kid in me gets all giddy because I get to work for one of the companies I grew up with. Many a dentist's office visit I spent searching for hidden pictures in a Highlights magazine. Here's a recent cover I got to create for an issue of a Highlights Puzzlemania book. The illustration also appears on the inside with a nearly identical version next to it with 20 differences to find. Check out the pics below in case you're stuck in a dentist's office with nothing to do.
