Several different governmental departments used their own overprints on the official stamps of South Australia between 1868 and 1903. Many of these stamps used a general overprint, ‘OS’, meaning official stamp. However, several others used specific overprints — for example, ‘P’ (Police), ‘BG’ (Botanical Gardens), ‘EB’ (Education Board), ‘VN’ (Vaccinations), and ‘GT’ (Goolwa Tramway), to name but a few.
