Nintendo gave these at E3 2005 to promote The Legend of Zelda: Twilight Princess. The cartridge itself is just a trailer packed in a press kit. This is a really cool item. There’s only a few of these that would pop up on eBay every year. Who knows how much it’ll fetch this time around. If you’re a Zelda fan or just a collector, this is definitely a must have.
