This is a very old unused black & white/sepia postcard of St. Columba’s Bay Iona. I don't know the exact age of this card, but it looks like it is from the early to mid 1900s. It is a Real Photograph Post Card, by D B MacCulloch, numbered 484/106 and the card is in very good condition - no creases, or obvious marks, even the corners remain mostly sharp.
