Oppenheimer's work was exhibited in the International Sonderbund in Cologne in 1912 along with the work of two other women artists, Marie Laurencin and Paula Modersohn-Becker. The next year, in 1913, she participated in an exhibition of Rhenish Expressionists at Walter Cohen's Bookstore, put together by August Macke, an influential Expressionist painter himself.
