i received several unpunished cardboards as part of a "pay it forward" thread i participated in on a FB page. i want to preface that the cardboards where included as a "bonus" so i am in no position to complain either way. As i am grateful for the package and find it a little inappropriate to question the integrity of the gift, i feel it is best suited to post here for feeback whether they are authentic or not and most of all, some education on how to tell.
i am loose collector so i know little to nothing on judging the authenticity of these cards. my gut tells hell no and that they are repro due to condition. Thanks for looking!

They are all fake, for example look at how far the Luke & Leia image enters the racetrack border

thanks Aussie James, im looking but don't see the difference between the one you posted. i get that these are all fake, they will never be passed along and prob used a coaster or shim for a wobbly table..

appreciate the schooling on this. if there is thread out there please post

thanks again

I'd say they are fake as well.  They look too perfect.  Some of colours look a little off as well.
I would check to see if they are made in multiple layers or on one piece of cardboard.
Plus they look like they have never had bubbles glued to them.

I'm not sure if there is a thread about how to spot a fake card back? But if you look at the card back using a magnifying glass, and if it was printed on an inkjet printer, you should be able to see all the little dots.

Here are a couple of quick links.

Definitely no bubble was ever attached.. I will dig out the magnifier.

I see now how Luke's leg enters the raceway to much. Thanks

Thanks for the links Clint
