Fifty-three undated watercolours intended as bookmarks, each 200 x 45 mm in size, sold by John Sands of Sydney as indicated by stickers pasted onto the reverse. The images are of birds, with the exception of two koala bears, two kangaroos and one opossum. The vast majority are the work of three authors, signed Artah, M. Simpson and Koddi. Artah is Violet Artah Bartlett, an artist specialising in Australian ornithology who worked in Sydney during the 1920s. It has proved impossible as yet to gather information about the other two artists. One watercolour is unsigned. Pencil notes on the backs of the bookmarks identifying their subjects have been reproduced in square brackets.
