Here is why I think the information given in the Bully museum catalogue is wrong!!
Also be aware about the information about the markings, molds ect. then you also see that those are in logic order. Same thing with the articlenumbers. The Bully articlenumbers are given in the EXACT order as they are sold according to the posters, markings, molds etc.
Just like W Berrie in the US did. When releasing a new smurf they gave it a new articlenumber. Just read the W berrie catalogues!! Same with Schleich. The articlenumbers are given in the exact order they were sold. Though Schleich had to jump in the articlenumber serie because they reached numbers they already used.
