On this paper you can see that this was the first official and complete collecting catalogue for smurfs made by Schleich and they even call it a historical moment( ein Stück zeitgeschichte( I hope I translated this correct Tojo, Maureen, Stefan or other germanspeaking members))
They also tell us that they had produced 301 smurfs to that date.
But regarding the train. They tell us this was going to be released in autumn 1986 and was developed together with Märklin. So there are most certainly at least one train somewhere.
But because of the financialproblems ( you can read about them in the SCCI letters from these years on Maureens site) they dropped the train and almost half of the smurfs released 1986 comapred to 1987.
By the way I don´t know if Schleich ever made any more collecting catalogue for smurfs??? All others are made by other companies, sellers, etc?? Do any of you know anymore catalogue made by Schleich??
