The paper discusses the Garboldisham macehead: an unusual decorated macehead carved from red deer antler. The macehead was found in the 1960s deposited in a tributary of the river Little Ouse, Norfolk and is decorated with three spirals, making it especially significant. This paper reports on the analysis of the decoration using digital imaging, discusses a new radiocarbon date recently obtained for the artefact, and discusses its significance alongside other dated antler maceheads.
