It goes without saying that Wales - as part of the United Kingdom - is served by Royal Mail, so labels like these inscribed "Cymru" are purely Cinderellas, issued for fun, and with no postal validity.
The creator of these issues produced his first Cymru labels in 2015, with several different sets appearing each year. Topics are always Wales-related, embracing everything from St David's Day to Welsh pioneers, food, architecture and landscapes.
Past issues can be obtained from caz1961carole on eBay.
