The Secret of Monkey Island: Special Edition Guybrush vs. LeChuck Statue
A statue made to celebrate the release of The Secret of Monkey Island: Special Edition. It measures to 10-inches tall, made from resin, fully painted and packaged in an illustrated box. Only 1000 copies were made and only available via the official Star Wars shop. The description for the item says:
"In case you haven't already heard, legendary game title Monkey Island was just made available as a Special Edition release, bringing back the adventures of Guybrush Threepwood and his epic battle against the evil ghost pirate LeChuck!
StarWarsShop has commissioned this exclusive polyresin statue of Guybrush battling LeChuck in one of the game's final sequences. Depicted is essentially the last 'battle' in the game, where LeChuck is punching Guybrush so far that he flies into different locations previously visited in the game, only to have LeChuck appear there to punch him again. That process goes on until they land at Stan's Used Ship Emporium where Guybrush sprays LeChuck with root beer, which he previously found out is a magic ghost-fighting elixir."
The 10-inch tall statue, shown here in its protoype state, is made from resin and will be full color and packaged in a stunning illustrated box. The edition is set at a maximum of 1,000 made worldwide making this an ultimate collectible."<cite_reference_link>
