Margaret Preston
(1875 - 1963)
 

Margaret Rose Preston was an Australian painter and printmaker who is regarded as one of Australia's leading modernists of the early 20th century.[1] In her quest to foster an Australian "national art", she was also one of the first non-Indigenous Australian artists to use Aboriginal motifs in her work.[1] Her works are distinctively signed MP.
