 No works survive that can be securely attributed to Verhulst, although she is frequently identified as the person behind several works assigned to the Master of the Brunswick Monogram.Verhulst may also have been the author of a painting in the Kunsthaus Zürich with a self-portrait with her husband (panel, 50.5 x 59 cm).While little is definitively known about her life and works, Guicciardini's "Descrittione" places her alongside Susanna Horenbout, Levina Teerlinc, and Caterina van Hemessen, suggesting her remarkable talents.
