These four cards were including in specially marked packs of Kelloggs cereal and milk snack bars. There were three or four different types of snack bars - including Frosties, Cocoa Pops, Ricies, and maybe even one other. I think I kept the boxes, but I'm not quite sure where I put them. If they turn up, I'll scan them in.
I saw these cards available in the United Kingdom, and I've also been told they appeared in France. I managed to acquire three of the four different cards. I would be very happy to get a hold of the card I'm missing. I have doubles of the other cards to trade, so if you can do a swap, please Mail Me and let's trade.
The cards themselves are smaller than regular trading cards. They have rounded corners, and are actually quite attractive. The front depicts a prismatic 3D scene from the 2004 movie. The 3D effect is excellent, and has great coloring and lighting. The scan doesn't do these lovely cards any justice, they are some of the finest prismatic engineering I have ever seen.
No number is given on the card, I have assigned numbers arbitrarily for tracking purposes.
