There's no Comic-Con International in San Diego this July but there'll be one in a four-issue mini-series that comes out this July…Groo Meets Tarzan. Much of it is set at that con so you will be able to see a frighteningly-accurate vision of what would happen at that convention if they had it.
You'll also be able to see two great warriors — Edgar Rice Burroughs' majestic Tarzan and Sergio Aragonés' moronic Groo the Wanderer — come together in a story so unbelievable that I don't even believe it and I was actually there when it happened. Sergio and I appear in the story along with our title stars. The fine illustrator Tom Yeates drew Tarzan and the scenes in that hero's world. Sergio drew the rest and there was lettering by Stan Sakai and coloring by Tom Luth. More details can be found here.
