This fur muff first raised suspicions when it was selected for display. The uniformity of the colour of the pelt and strangeness of its features necessitated closer investigation. Beginning with x-radiography, NGV conservators were able to identify the fur as a construction: it is comprised of three sections with separately attached seamed tubes for the paws and ears. Additional fibre analysis of individual hairs using microscopy, coupled with advice from expert biologist Barbara Triggs, confirmed the pelt as a species of fox. As valuable furs became scarce in the early twentieth century, the use of cheaper skins that were dyed to look like expensive furs became accepted industry practice.
