i've contacted the seller, i'll try to traduce his response in english :
"i'm lucky enough to know the project-director that offered me those 6 prototypes.
I've followed the post-production of this project with high attention. that's why i've got some drawings i'm allowed to use. But be carreful thoses photos are protected by an international copyright so thank you to respect that.
And what i can say you, that it's impressive to see each step from the first drawing to the prototype.
This collection will be available first in a big video game distributor in France.
There will be more than 30 figures for this 1st serie.
This is not a cartoon project, not that far i guess, it's a copyright and a game board that will be also available and card to collect too."
Thanks to him for his response !
