OK, I'm not collecting the Indiana Jones Heritage cards and don't know anything about them. However, I did buy the ROTLA DVD at Circuit City today and it included a 3-pack of cards. They appear to be regular base cards (and all the DVD's had the same top card). The other 2 DVD's had different 3-packs (and again all the DVD's had the same top card).
So I guess the only thing special about the cards is that they are wrapped together in cellophane.

Anyway, if anyone wants these to "complete" their set just let me know. We can work out a SASE or something.
