If you are really grateful to Kenner for the Star Wars toy line as your name suggests then do the toys some justice by not going down the repro/custom cardback route.
There are alternatives to lining Nathan Edwards pockets..(the Spain based repro seller) You could actually purchase vintage carded figures for starters or just get some acrylic cases to protect them. You could even make a custom display case with a nod to the cardbacks..
I'm going to be locking this one up just like your other thread as the forums tolerance level for repro discussion threads isn't very high. Please refer to previous threads for more information using the search button top right, or just understand that the majority of collectors think reproduction cards are detrimental to the hobby and you should never give them another thought.
