At first I thought that Bully never manage to sell any of the last 16 smurfs they made in 1979.
But thanks to Benny, who found these pictures on another smurfsite, we can see that at least they managed to send in these ads before they lost the rights for the smurfs in 31st of December 1979.
The picture of the last 8 smurfs is from an ad dated december 1979. And as you see they show colourvariations that I don´t think ever was sold. So the last 8 smurfs maybe did not get to production before Schleich got the molds and sold these in their catalogue for 1980.
Anyway it is very nice to see these smurfs together with the bully figuren emblem as I know have of almost all the other Bullysmurfs. Except the ones sold in spring 1979. Smurfs 20101-20105.
