Your second picture wasn't there when I posted above.
Take a look at the picture to see whether it's printed directly onto the box or stuck onto it. If it's actually printed you might have discovered an extremely rare tape (although I'd still have my doubts!). If it's stuck on then it's almost certainly homemade.
Actually, on looking again, I see that there's a crease mark across the picture at the bottom right. Since it's not there at the bottom-left, I'm guessing that 4 separate photos (probably cut from one of the magazines which you could buy from cinemas at that time) have been stuck onto the box.
