Here's the story with German cardbacks.
http://www.raumhafen.de/cgi-bin/showp.pl?pic=/galerie/starwars/sw/esb_45back_d&titel=German%20ESB%20Figures
In summary there are 2 types:-
One has "STAR WARS ACTION FIGURES Collect all 45!" written on the back, the other doesnt.
Wolfgang notes that his 30 used cardbacks which were shop sold in Germany (with wear and price tags etc) are all the type without text.
Same is true for my collection of used German cardbacks. Not one has the writing on the back.
(I'm missing just an ESB Lobot to complete this run if anyone knows of one for sale).
All of the MOC that I have see out there have the writing on the back. None have price stickers indicating they were shop sold.
All cards of this type are minty mint and very few have been opened.
There are very few examples of MOC without the writing on the back.
So here's what I think happened.
These cards were produced in the Palitoy factory, initially with the "STAR WARS ACTION FIGURES Collect all 45!" text on the back.
These cards were pulled and not released to the German market because it was thought the English text on the back was not appropriate
for the German market. The cards were all stored in the factory and not released. The text was then removed and more cards were
produced which all made it to the German market. When the factory closed, Arthur bought the unused stock including these unreleased cards.
Toni then bought them all off him and has been trickling them into the general collectors market ever since. Almost all MOC that are out there in collectors
hands have originated from Toni and the unreleased cards from the Palitoy factory.
And thats it. I haven't commented on whether the unreleased cards were assembled at the factory or later from their components as that is
in dispute given the commentary from JJ and Toni.
That pretty much explains the cards we see today and their condition and whether they have price stickers on them or not.
