Tomi Ungerer's inexorable ascent began in the fifties in New York - with commercial artwork. Since then a central element has reccurred in his multi-layered work: Tomi Ungerer, the drawer, painter, illustrator, narrative writer, author of children's books, has created hundreds of posters. This book shows a cross-section thereof: the beginnings in America, advertising work and deadly serious social criticism, posters for music and the theatre, for Strasbourg and the Alsace, for humanitarian campaigns and organisations - and posters for children over and over again.
