Tout Hergé, Belgium.

Original vintage poster about an exhibition called “Tout Hergé” which took place in Welkenraedr, Belgium in 1991.
I got this poster from a Tintin collector who came to this exhibition because he was visiting his sister who lived in Belgium and had so much stuff in her house that he wanted to get rid of some objects.
