Richie Rich & Casper #11

Harvey's cheerful crossover title brings together Richie Rich, the Poor Little Rich Boy, and Casper, the Friendly Ghost, for another delightful adventure in this 1976 issue. The cover sets up a wonderfully puzzling scene outside R.R. Lab, where a small figure — dressed just like Richie, complete with red bow tie, but invisible from the neck up — stumps the duo, with Casper exclaiming the Invisible Kid looks like Richie while Richie insists the smile is different. The tagline promises "a laugh-filled thriller that's out of sight," and with a mystery this charmingly absurd, it's hard not to want to see how it all plays out.
