Here's a pic of a poster i picked up either Passion or in Utrecht which has some info on it...the markings were:
Association Des Paralyses De France
© Peyo 1994 I.M.P.S. (Brussels)

Maybe someone who can read French can translate the wording up the top and let us know if there is anything else interesting mentioned on the poster, for those of us who cannot not read French might benefit from
