Gert Sellheim, (Estonia, Australia, 1901-1970). Australia [Boomerang], 1957 colour and process lithograph, signed in image upper right, 100 x 63 cm. Linen-backed. Text continues 'Australian National Travel Association, Railway Building, Flinders Street, Melbourne. 153 Kearny Street, San Francisco, Cal., USA. Litho., McLaren & Co. Pty Ltd, Melbourne, Australia. No. 115.', The appropriation of Aboriginal imagery became a characteristic of postwar, modernism within Australian art and culture. To achieve a distinctly Australian look, inspiration for travel posters was drawn from the X-ray art style, from rock paintings, and from Aboriginal material culture. Aboriginal motifs, such as the boomerang, were often tempered with non-Aboriginal motifs such as swimsuit-clad women or sheep.
