In addition to the 3 "Classic Style" Sonic figures, First4Figures has done an extra special 12 inch figure, and this is it!
Classic Sonic, of course. This large size figure is on a detailed base, with the well-known checkered Green Hill Zone ground and overlaid 'grass'. If you look carefully, you can even see that the surface of the grass has tiny bumps. The classic Sonic itself looks good from this angle, capturing the classic feel well. (thin arms/legs with round circle body and simplified shoes) They've chosen a bit of an odd pose as he is touching his nose for some reason...but that doesn't stop the statue from looking good. And it's a good thing too, as each one is $99.00 USD!
They are also limited run, which means that only 1500 will be available for sale, adding to the scarcity.
Here's a prototype image of the statue, where his eyes are more narrow. It's good they changed it as the final version is much more accurate. 
Made in high quality polystone resin, he comes in deluxe full color packaging, hand numbered base, and includes an Authenticity Card which allows you to purchase the same number of the model next in the Classic Sonic the Hedgehog series. The artist who sculpted it was Lu Bin.
Original photos by First4Figures. The statue was scheduled for September 2008 but the final release ended up being in May 2009.
Did you know? F4F goes the extra mile with their statue figures and includes a plastic card with the unique code/number of the figure you got. In this case, it's for a classic display figure. (All the cards are either classic style or modern style, and they look the same) You can see they used real raised embossing for the code on the thick plastic card. What a nice detail.
