Numerous post offices in Australia feature pictorial postmarks. One notable example is SA 15.1a, which has been canceled in Devonport and depicts a lighthouse. According to the Devonport city guide, “The Mersey Bluff Lighthouse, with its distinctive red and white stripes, has stood watch over Devonport, Tasmania for over a century.” Built in 1889, the Mersey Bluff Lighthouse is a significant historic symbol for Devonport, representing both the city and Tasmania’s rich maritime heritage. Its iconic appearance makes it a cherished landmark for both locals and visitors.
