This depiction of the artist's family was completed in 1927 after the birth of Otto and Martha's second child, Ursus. Four-year-old Nelly hides behind her mother and offers a flower to the infant.
This painting is noteworthy for its self-deprecation. While he was quick accentuate the worst features in others, Dix generally portrayed himself in a flattering manner. Here young Ursus has reduced Dix to a blithering idiot. He coos and makes faces at the boy. (http://www.ottodix.org/catalog-paintings/page/4/)
