There were a couple of postage stamp issues in 2003 that featured windmills.
- Malta - 29/9/2003 - set of 3 stamps,
11c: Former Valletta Windmills,
27c: Mithna ta' Kola (Xaghra, Gozo)
45c: Mithna tax-Xarolla (Zurrieq)
(The Malta Post
page seems to have given up part way through the year!)
- Sweden - 20/3/03 - a set of 4 stamps showing The Öland Moorland -
World Heritage 3, of which the first shows the field of windmills
(The page from
Sweden Post shows that the Year Set also carried
further images of the windmills).
The Stamp C@fe has a page showing the windmills new issues in
2004
(if any come out!),
2003,
2002.
