That is the production sculpt and is what should be in your box as it's what is in everyone else's. Open your figure and compare it with the eBay pic, you should find that they are exactly the same head. If not, then, wonder of wonders, you have scored a pre-production piece which is worth a small fortune. If you still want help on here then I suggest you show people what you have and they can decide if it's a production figure, like even I suspect it is, or you got a rarity.
You will never know what you have till you open it
