This is still the early version of the card itself, but containing the later, revised copy of the Nuclear Freighter, held in a new, revised blister. I believe Roxy will have used up remaining stocks of the original backing card in Europe (this particular example was found in Amsterdam), where "Golden Astronauts" wasn't used as a trademark.
