'At my desk in the Mitchell Library Reading Room I picked out a small cardboard folder from the pile of books and boxes beside me. Opening it I carefully removed a thin envelope, an item I had been curious to inspect after finding it listed in the library catalogue. ‘The ‘invisible hair net’: fully sterilized / made expressly for David Jones Sydney’, was, according to the catalogue summary, a ‘Specimen of a hair net packaged in an envelope. The packaging includes a black and white illustration of a woman with styled hair, presumably the result of wearing the invisible hair net.’' (Introduction)
