In 1989 Casterman and Rijperman released the first color album version of the Johan and Stefan album "De Zondebokken" ("Les Bouts Emissaires" in French, and "De Geitenrijders" in the original Flemish version which was also the very first Snow en Snolleke album ever). For that reedition Bob De Moor would prepare a lot of different versions of the cover artwork.
