This is part of a game-book series by "Hachette Jeunesse," in which the goal is to seek and find a few characters in each double-page landscape. If you like these, I previously rounded up some cool Where's Waldo/Wally panoramas here.
In this particular book there are 12 such games to play, and I'll give you one of my favorites, The Boarding Party. Click or zoom the images to expand:
The goal is to
find these six!
Now here's the puzzle:
From what I understand, Uderzo himself did the art, and the book was originally published in 2010. I'll edit in the answer key in a couple days!
HINT: Idéfix being the smallest is really hard to spot, but I can tell you that he's not on the two ships, and you can only see his head.
The placement of the dog is just evil.
Haha, truly.
I'm guessing that since the character number is much smaller than a typical "Waldo" layout, they decided to make one similarly hard to spot. OTOH, I like how they presented a range of sizes to find, hopefully to meet a variety of solving skills, or at least patience level(!)
