In Cižek's course, "Theory of Ornamental Form", Klien was introduced to a new style known as Viennese Kineticism – a style that emphasized movement and modern vitality, in a way similar to French Cubism, Italian Futurism and Russian Constructivism.

[1] After graduation, Klien found it difficult, as did many women, to earn a living as an independent artist.

She worked as a commercial graphic artist and taught at the Elizabeth Duncan School, at Klessheim near Salzburg, from 1926 to 1928.

[1] Klien's work was included in several international exhibitions, such as the Paris Decorative Arts Exhibition of 1925, the Armory Show in New York City in 1927 and the Fourth International Congress of Art Education in Prague in 1928.

In 1929 Klien sailed for the United States, bringing with her hopes for an artistic career and the reform theories of children's art education she had acquired in Vienna.
