I love the artwork for A Con Artist in Paris- nice! Of course, I find it very reminiscent of the cover (http://www.hardyboysonline.net/content.php?page=cover&id=hb-179) to The Hardy Boys #179 Passport to Danger, which I also thought was really cool. :) 8)
The skateboarding cat thing in the Clues book seems about 5 years or so late, but that's cool. (There was a deal some years back about a skateboarding dog on Youtube, I believe... I mainly remember it because The Muppets parodied it with a video of Rowlf as a skateboarding dog.)
