Eh- since I was going camera crazy tonight anyway, and since I have talked about this sticker variant, I figured I'd post the pics of it here...
...and yes, I shelled out more $$$ for a sealed one with the WHITE sticker...sad, eh?
As far as rarity? It appears that they're about equal in quantity. On Hasbro's site in their archives they show the sticker highlighting the Falcon that DOES NOT have any white on it. I couldn't tell you if that makes the white one rarer.
Enjoy, variation hunters
