Thank you Cardbackkid (sorry I don't know your name).
Ah ok, so from the 65bk's onward is when Palitoy started using the dropped black bar below the logo on the front. Before on the ROTJ card's the ROTJ logo was like the Kenner ones just with the blank Palitoy space at the bottom.
By the way I can't find anywhere a photo of a Palitoy Power Droid 45bk ROTJ.
Do you know of any other figures that are known not to have surfaced this way?
