It was written 2003.
To me it seems Hugues Dayez wants to tell us how Peyo got the right the the smurffigurines and Dupuis didn´t want a part of this. And this turned out to be a big mistake with the success all over the world.
And since it was the Schleichsmurfs that was the first made with only peyo as "copyright" it probably is about the first Schleichsmurfs??
Would be lovely to see a cornflakes box with a Schleichsmurf inside!!!
