Are you looking to invest in some virtual property? Do you have a ton of money at your disposal? Even if you answered "no" to these questions, you should take a look at the intriguing sale that's coming up in Planet Calypso, an MMO with a real money economy. The Medusa's Head islands are available for viewing today for potential buyers in preparation for the auction, which will be held from Dec. 13 to Jan. 3. According to First Planet Company, developer and publisher of Planet Calypso, this will be the largest virtual property ever sold.

This sale has the potential to be one for the record books. Last month, a small virtual resort in the game sold for $635,000 after originally being bought for $100,000 in 2005. This piece of property was previously in the Guinness World Records book as the most valuable virtual item.

So what's the price tag on the Medusa's Head islands? Only time will tell, but the property is huge. It encompasses eight different revenue-generating land areas and includes two unique creatures that will be of interest to hunters. You can view a map of the islands after the jump.
