Mixing up boxes happened plenty in Europe too, but most people just didn't and still don't realise!
I would expect the 'realistic' box to be an early release and then they moved to the 'cartoon' box, judging by the availability of inners. But who knows.
Well this looks to be an alternative cover to TB2 I've never seen before! Always wondered if there was a version with the 'realistic' artwork on the box. I have the 'cartoon' version box but the manual and cart are the same as yours.
