I agree - I dont like the base of this jar either. It looks like one of the early fakes in this colour we saw floating about in early 2007. I'd be asking for more pics of the base, back and box as well.
Update: This seller answered one question of mine but has not gotten back to me on the picture. Feels shady, especially since the questions were sent via same method and within minutes of each other.
Thanks again, guys!
