A puzzle!
This is an uncommon puzzle from France. It seems to have a little bit of combination art on it. The Sonic/wooden bridge bit looks like Game Gear game cover type stuff, but then look at cute little "lookin' out" Tails there. He's CERTAIN to be a seldom-seen Japanese stock art piece because he is actually cute and well done. (Remember this was the era where they let out less than stellar Tails art and started mis-coloring him sometimes too, in merch)
You've got Eggman up there in an Egg o Matic, some Buzz Bombers, a Batbrain, a Newttron & a chop chop fish too. The sky is mostly pink, and with the light green grass and light blue water, it gives the puzzle a mostly pastel look, save for Sonic himself and the badnicks. It's almost an 80s flavor to the art colors chosen.

This puzzle had a bonus, too:
It comes with that poster you see there of the picture, as well as the puzzle itself. It's a nice touch to include a real size poster. The box has "Funny Way" written on it but why? It's in English it would probably confuse French kids, is that the name of the line of puzzles? The actual maker of it is written in the white square there "Editions Nathan", although that part is difficult to read. Editions Nathan is famous in France for books & games.
