Ok, things are getting interesting now!
Bulbapedia says:
Pokémon Rolls were produced by General Mills under the Betty Crocker name and released in 1999. The product is candy rolled into a flat strip, similar to the popular brand Fruit by the Foot. Pokémon Rolls came only in “Punch Red” flavor and were sold in packs of six. Each box included a special Meowth promotional card for a limited time.
Jonathan Yusen, marketing manager of Betty Crocker, stated the following in regards to the rolls: “In order to keep our fruit snacks fun and entertaining, we love to work with equities that are hot with kids.”
The 1999 release don’t match the copyright of the cards.
Also, bulbapedia says only the promo meowth was given with this product (I kinda remember it wasn’t sure to find the gold border on every box, but let go for now).
This Box:
It's slightly different from the one above posted by @khairis , it was a different promotion (the one we most know, in partnership with wotc for the gold border meowth. So the cards given here were tcg card. BUT, there is still the other version, that states STICKER, not CARD.
And those “stickers” are clearly the ‘official nintendo promo cards’ (we can call them “Pokemon Rolls Sticker” now?) you can see in the front box blue border Primeape and Jigglypuff.
So, we’re close, but not done yet.
