Orovida's most distinctive works are her paintings of the 1920s and 1930s in gouache (she called her mixture 'bodycolour') and egg tempera, applied in thin, delicate washes to silk, linen, paper or gold leaf, and embellished with brocade borders. 'Waterhogs' is related to an etching entitled 'Pigs', printed in 1930, showing her taste for animal subjects.
