The article states that (will write just a few key points):
There are a total of 339 stickers
Croatian players are fetured on gold cards
45 best players are also drawn in the form of a caricature (see the pictures in the link)
All pictures are unique and drawn by an academic painter
Every sticker of a football player also has a: Date of birth, Playing position, Market value (taken from the Transfermarkt site) and a Stronger foot symbol. The quality of player is also estimated with the number of stars from 1 to 5 (don't ask me how they decided on how many stars to use for an individual player).
There's no checklist for now, but they included Wayne Rooney, Panini will not do that, at least I hope.
You can also win some awards if you collecet the right number of packs, etc.
That's what I was able to find online, I don't and will not have any scans available as this is not my type of collection...
