If it really is a vanilla it's a great deal. The question is, is it a reputable person selling it? You need to find out if he produced it from a proven vanilla, or who he purchased it from. It IS light, but I've never seen a Vanilla with a black back pattern. That's not to say it can't happen, but I'd be 100% sure that I'm getting an actual Vanilla first. I'd be awfully mad if I bought one, put it to a fire, and never produced a single Vanilla Creme with it.
I also can't see the head stamp in this pic. I'd get a good head shot and a belly shot. The belly of a Vanilla is usually mostly clean.
