If you don't want to post a picture, you could also just tell us what the antenna looks like or the design of it, I'm sure most of us would be able to tell you what version it is. xP
Whoa cool! That's a rare Tama (as binary said, a P2)! Since it's still in the box, you could probably sell it for over $100, if you wanted to sell it that is.
If you're into Tamas or want to collect them, I'd definitely keep it though!
