I'm not 100% certain, but as an avid POTF 2 collector, I've never seen nor heard of this.
The purple backs were for "Shadow of the Empire" figures.
All of those cards (once again, as far as I know) have the diagonal light and not the vertical one.
If we could get a better quality picture and maybe a picture of the projection card, that would be easier to figure out what's up!

Thank for the reply, this is the only other pic i have. I will try and get my friend to post some more
Judging by the spelling mistakes on the card I very much doubt it is official.
It's not anything official, back in the early days people would create various POTF2 type figures/cards for conventions so it's most likely something along those lines. As for the signatures, they'd need to be authenticated to make sure those are real.
