We have a new country to discuss! On 14 Dec 2020, Tristan da Cunha issued a set of 13 definitive stamps picturing modern mail ships. Since Tristan da Cunha is a remote island in the South Atlantic these ships are important to its economy. The £5.00 stamp shows a ship that looks nothing like a lightship but it, in fact, began life as the lightship Elbe 3 in 1911. After being retired it was rebuilt as an adventure cruise ship named EuropaFormer lightship Elbe 3 | 14 Dec 2020
Thanks to Jaap for finding this unusual stamp.
