Michael Graham-Stewart is an independent art collector and dealer, working with a wide range of media and subjects. His focus is on the spaces between cultures, as articulated through art and other cultural objects: drawings, paintings, prints, carvings, photographs, flags, books, breastplates, periodicals, ephemera, etc. His first publication was Africa: Relics of the Colonial Era; his most recent is Surveyor/policeman: two amateur antipodean photographers. He has produced several books of photographs of indigenous peoples, including Out of Time: Māori & the Photographer 1860-1940, Surviving the Lens, Framing the Native: Constructed Portraits of Indigenous Peoples, Negative Kept: Māori and the carte de visite, and 4Africa. In addition, there have been volumes covering material culture, such as The Mlungu in Africa and South East African Beadwork, as well as a series of themed catalogues, including About Strange Lands and People, Far Away and Long Ago, WARS: War, Art, Racism and Slavery, Crombie to Burton: early New Zealand photography, and Fiji Times. His largest accumulation to date was of images and artefacts pertaining to slavery. Future projects include Jesus in the Pacific, a collection of materials relating to Christianity in the South Seas, and Bitter Fruit, photographs of Aboriginal Australians from earliest times to 1962.
