Court life and dynastic role Following her marriage in 1886, Maria Theresa assumed extensive ceremonial duties within the imperial court, dividing her time between the family's urban estates in Vienna and their permanent residence at Żywiec Castle in Galicia. An accomplished watercolorist and landscape painter, she actively engaged in artistic patronage and professional artwork production throughout her tenure within the imperial family. Utilizing the monogram "MT" for her signed creations, she specialized in botanical illustrations, historical architecture drawings, and regional landscapes, including her notable 1918 watercolor piece titled Seenlandschaft.

Her private artistic portfolio remained formally integrated into the family inventories of the House of Austria-Tuscany. During the interwar era, following the institutional sụp đổ of the Austro-Hungarian Empire, she retired from public court obligations to focus entirely on family affairs and her private studio in Europe. Portions of her verified dynastic artwork collections and signed landscape paintings were preserved across regional aristocratic estates and subsequently documented by contemporary curators and art market specialists through the late twentieth century.
