Can anyone tell me what this is worth?

[T-U-R-T-L-E POWA!]

I have a poster of Raph from the first film and it's framed and I've had it since it came out originally. My papaw framed pictures for a living and he put it in a frame for me. I got curious about it the other day and looked on Ebay to see what they were going for and one that wasn't in too great of a shape was going for $52. Any suggestions on what an absolute mint one would be worth? Here's a picture of it. It is not MY poster but just a picture of the poster I am talking about. Any help would be appreciated.

Well I ran a search for sold listing on ebay and this is all that came up.

It went for only 14 bucks :(
Personally I would keep it! But if you are really strapped for cash I would stick 200 Or best offer on it and see where it goes.

Thanks man. I would really hate to part with it but thought maybe I could use it to get some cash to help get some figures I would like to have. I'm also trying to build my Real Ghostbusters collection back as well so that gets pretty pricey. The MIB Real Ghostbusters are OUTRAGEOUS! Over $300 a piece STARTING price!
