Yes, it's the blurred one. I first saw it on the T-Shirt photo of the sponsored football club. That one was a non-blurred version, but the ripples rendered it unusable.
I saw the mentioned ones too, but the blur makes very hard to trace it's contours (not impossible I have to admit, but authenticity... :-))
I could trace it with bezier curves then enlarge it, but that's simply not the original one.
