As soon as it was possible for Friedrich M. Welz after the war, he took over the management of the gallery again. In addition to numerous exhibitions in his own gallery, he also planned and realized many international arrangements, including the 1957 exhibition “The Classics of Austrian Modern Art from Klimt to Wotruba” at the Württembergischer Kunstverein in Stuttgart as well as various traveling exhibitions for Giacomo Manzù, Wilhelm Thöny, Oskar Kokoschka and Alfred Hrdlicka.
