The daughter of artist John G. Sowerby,
illustrations graced many
popular children's books, including Lew Carroll's Alice in Wonderland (1907), and Robert Lewis
Stevenson's A Child's
Garden of Verse (1909).
Her skill was mostly self-taught, studying the work of other
illustrators. She collaborated with her sister, Githa, on
books over a twenty year period.
Her postcard illustrations often depict children, fairies, fairy tales
and nursery rhymes.
