I'm not sure if they hired a third rate cover artist or if this is intentionally not supposed to look like William Shatner -- Shatner's "appearance" in Season One of Family Guy looked more like him than this! -- but that's supposed to be everyone's favorite overacting starship captain. From Amazon:
It's Shatner VS Shatners! William Shatner? William Shatner. WILLIAM SHATNER!!! It's the first ShatnerCon with William Shatner as the guest of honor! But after a failed terrorist attack by Campbellians, a crazy terrorist cult that worships Bruce Campbell, all of the characters ever played by William Shatner are suddenly sucked into our world. Their mission: hunt down and destroy the real William Shatner. Featuring: Captain Kirk, TJ Hooker, Denny Crane, Rescue 911 Shatner, Singer Shatner, Shakespearean Shatner, Twilight Zone Shatner, Cartoon Kirk, Esperanto Shatner, Priceline Shatner, SNL Shatner, and - of course - William Shatner! No costumed con-goer will be spared in their wave of destruction, no redshirt will make it out alive, and not even the Klingons will be able to stand up to a deranged Captain Kirk with a lightsaber. But these Shatner-clones are about to learn a hard lesson...that the real William Shatner doesn't take crap from anybody. Not even himself. It's Shatnertastic!
