Paintings and drawings
Waleria was a miniaturist, painting portraits and religious subjects. She often signed her works "V. T.", and depicted miniatures on ivory, usually with watercolour, sometimes with gouache and watercolour or only gouache. Her paintings are often miniature copies of paintings by other painters, and portraits of family members.
