Tusnelda Sanders (born Frida Nielsen, 1894–1978) was a noted Danish primitivist painter and illustrator whose works were sold both in France and in North American galleries from 1944 until her death. Her graphic illustrations were used in books and posters. From the 1920s until her death, she lived and made art in Cagnes-sur-Mer, the artists' colony on the Cote d’Azur near Nice, France. Her works are signed with the single name, "Tusnelda." Her unofficial name-change to Tusnelda in midlife awaits explanation.
