What kind of cards are these?

I found a bunch of these cards today. Buddy had a whole lot more for other game titles and doubles. I've honestly never seen these before, what the hell are they? They got a bunch of scratch off portions on them..in retrospect I should have bought some of the doubles just so I could scratch a couple and see. It appears to be some kind of contest or something? Or just collectable "game" cards?

 

Aww crap I remember these! I think they came in packs of gum or something like that.


EDIT:
found it!

Oh nice! The Nintendo Gamepak (certainly not a tie in name at all!)

I love the old school art on them, something about the Nintendo cartoon drawings from pre 1995 were the best.

 

I had a few it extended to 3rd party games too with Double Dragon cards too.

 

The dude did have some Double Dragon ones, as well as Punch Out. I just picked out the Mario ones though =P

 

These cards were my first glimpse into Mission 4 of Double Dragon.

 

This cards look fun. Can you scan them?

 

I'd have to get my hands on a scanner, but I don't see why not.
