Almost unbelievably, Tanera Mor shares one characteristic only with Lundy in south-west England and Caldey Island off the coast of Tenby, Wales out of all the islands that form part of the UK. It issues its own postage stamps, which are valid throughout the UK. Currently valid stamps only cost their face value and make a talking point! Of course there are numerous historic sets on sale as well at the 'Post Office.' (http://www.summer-isles.c...)
