Paul Klee

Paul Klee is not mentioned in the provided news articles. The articles focus on two distinct subjects: Manfred Schoof, a German jazz trumpeter and educator celebrating his 90th birthday, and the Salon du Dessin, a prominent international fair for drawings held in Paris. The article about Schoof highlights his collaborative approach to jazz music and his extensive discography. The second article features an interview with two German exhibitors at the Salon du Dessin, discussing their passion for works on paper and the significance of the fair. Neither article provides any information related to Paul Klee, making it impossible to create a summary about him based on the given context. Therefore, any summary about Paul Klee would be based on external information, not the provided articles.
