Sketches, mainly in pencil and crayon, made by Olive Muriel Pink of flowers found in the north of South Australia, Central and North Australia. The majority were made between June and December 1930, at various places along the railway between Port Augusta and Alice Springs. Later sketches were made in various parts of Australia between 1931 and 1960, but often without a note of the place and date. The sketches were often hurriedly made on pieces of thin, cheap paper, or even pieces of cardboard or brown paper. Some were coloured with crayon and a few, more finished drawings were coloured with watercolours. A later donation was made of books, personal belongings and sketches. A second series was received from the family of Olive Pink in 2016, this series includes Olive Pink's book collection, photographs, paintings, letters, items of clothing and other ephemera and memorabilia, some of which are nationally significant in their own right - such as the book plate made by Adrian Feint, notes and sketches done whilst camping with Daisy Bates, and photographs documenting life in Central Australia.
