The most important achievements of the publisher include the oeuvre catalog of Oskar Kokoschka’s paintings (1956), edited by Hans Maria Wingler, the work of Gustav Klimt with a catalog raisonné by Fritz Novotny and Johannes Dobai (1967), and the 4‑volume catalog of the drawings Gustav Klimts by Alice Strobl, edited by the Albertina Graphic Collection and the oeuvre catalog of the prints by Oskar Kokoschka (1975), edited by Hans Maria Wingler and Friedrich Welz. The most valuable work is certainly about Friedensreich Hundertwasser, by Werner Hofmann with a hundred color photographic plates with gold and silver, in the luxury edition bound in lambskin.
