Having put the first up for sale on eBay, Steve Purcell has done Monkey Island fans the favor of posting "the second of three" unused and unbelievable cover designs he did for LeChuck's Revenge up on his blog. This design, which depicts zombie LeChuck in his familiar, voodoo-torturing pose against the background of his storm-shrouded fortress, turned up in the Rogue Leaders art book and most recently yesterday's Purcell interview, but this is certainly the highest resolution we've ever had the pleasure of seeing the rare piece of painted piratey excellence in.
Speaking of LeChuck's Revenge, our post covering the ongoing Special Edition screenshot releases is getting unwieldy, so let me just say that Adventure Gamers has everything that's been posted so far in a convenient gallery.

This particular cover concept was NOT in Rogue Leaders, but it appeared at a really small size in the book's advertising campaign. Plus Telltale exhibited it at their booth at PAX last year.
