In the Deutsche Graphikschau Görlitz and in the Wallraf-Richartz Museum Cologne, graphics by Irmgart Wessel-Zumloh were confiscated by the National Socialists as degenerate art.
In 1957 Irmgart Wessel-Zumloh became a member of the Deutscher Künstlerbund (Association of German Artists), and from 1961 to 1967 she was on the board.
[2] In the volume Wegzeichen im Unbekannten – Neunzehn deutsche Maler zu Fragen der zeitgenössischen Kunst (Nineteen German Painters on Issues of Contemporary Art), published by Wolfgang Rothe in Heidelberg in 1962, Irmgart Wessel-Zumloh was the only woman represented.
[4] Irmgart took part in further international exhibitions in Salzburg, Madrid, Paris, Barcelona, Lille, Bruges, Buenos Aires, Montevideo, and Venice as well as in the US and New Zealand.
There are also exhibitions from classical modernism to contemporary, with a focus on early post-war art and thus the artistic environment of the Wessels.
