Dear Jenny Wilker,
There is a museum for "Bandes Dessinees" (comic books) in Brussels.
The address should be in the International Directory of the Arts since
it has been in existence for more than 5 years. Brussels, by the way,
is a center for such material and folks there should be able to steer
you in the direction of other institutions.
the address is:
Centre de la Bande Dessinee
rue des Sables, 20
1000 Brussels
Belgium
Sorry, I don't have a phone number.
Good luck.
