Thanks for the info. I was going to buy these retro boxes as a stand-in display for G1 deluxe Headmaters until/unless Takara or Hasbro reissues them, but won't do that now i know the new ones aren't the same size as the originals.
Well, the TF font,logo and motto on the top flap on these Walmart exclusives are coloured and worded as per the 1984-86 boxes. The 1987 Headmasters era boxes used different colours and a different motto, 'more ... much more than meets the eye'.
