There are many Scottish Isles that have jumped on the philatelic bandwagon, most of them for purely financial reasons, and most of them sporting such inane subjects as dog breeds, cat breeds, Olympics, and the British Royal Family (none of which shouts ALBA to this stamp enthusiast....), but Sanda Island at least has an image of its famed Elephant Rock and the Summer Isles at least depict Scots mythology....so even though none of them is recognized philatelically, these few are, at least, Scottisher than most of them.
