As a child I've always loved animal sticker albums, and panini was the best italian company to produce them. My favourite collection ever was this one called Animali Selvaggi (Savage Animals), wich contained size comparisons and accurate descriptions.
There were also special big boosters, with a regular booster pack plus one of the 40 plastic little animals or one of the 5 metal pins.
I had the complete collection of the figures (or at least almost completed) and with a bit of digging in some old chest of wonders I should be able to exhume 'em
I've seen that some of those little guys were not recognised in the "Brand identification topic" (I remember one of the apes and the muskox appearing there), so I decided to post the (not entire) serie leaflet for you.
