Last week saw the release of special issue stamps commemorating Queen Elizabeth II's Diamond Jubilee, however, not may people knew about these stamps, and not all post offices had them for sale (other than presentation packs, not likely to be used to send mail).
Royal Mail issues stamps celebrating the best of British, such as various eminent Britons, and the British institution, The Royal Society (with members from around the world, including Benjamin Franklin, an American, featured on the stamp for his work on electricity).
And then there are the fun stamps, featuring characters from Harry Potter (I didn't get many of these stamps, and they are no longer available from Royal Mail), to Discworld characters, music legends, and great stories...
Stamps can evoke emotions. On one letter I sent, I used a train stamp (not Thomas the Tank Engine or his friends) and this reminded her of her father who worked on the railways.
Then, as well as reminiscing about reading stories from Roald Dahl, there are comics, and cartoons... The Gerry Anderson issue even had a lenticular miniature sheet.
Plenty of great stamps issued by Royal Mail!
The next issue is out on 19th June 2012, celebrating the bicentenary of Charles Dickens' birth.
