Two stamps will be issued by the Island of Pabay as part of the celebrations to remember the battle of Flodden in 1513, in which an as many as 20,000 Scots were killed by an English army, led by the Earl of Surrey. Among the casualties were King James IV and most of the Scottish nobility.
Available on Monday September 9, the stamps will feature an image of the Flodden memorial on the battlefield in near Branxton, Northumberland and a stained-glass window commemorating the battle of Flodden from Middleton Church.
The privately owned island near to the Isle of Skye has been creating its own stamps since the 1960 and were created in collaboration between the island's 80-year-old postmaster, Jeff Harris and a German designer. He said: "I had the idea of a Flodden stamp. Pabay issues stamps with many Scottish connections and the Battle of Flodden is a major event in Scottish history."
The Battle of Flodden, the last great medieval battle, took place between King James IV and the English forces of Henry VIII led by Thomas Howard, Earl of Surrey.
Scotland suffered a crushing defeat and thousands were killed, including James.
The Island of Pabay stamps, which cost £2 and can be ordered by post or by email, are part of the many items and celebrations to remember the 500th anniversary on both sides of the Border.
The Flodden 1513 Ecomuseum project, which is the UK's first museum without walls, will be co-ordinating the anniversary commemorations. It is also supervising new excavations of the battlefield, which are set to take place between September 2 and 12.
The aim will be to locate and characterise any remains, so that evidence can be given to the government to allow the burials be declared war graves and protected from further intrusion.
The excavation will target the sites of body pits identified in the late 19th and early 20th centuries during works to lay water and drainage pipes.
