This is a very old unused black & white/sepia postcard of Godrevy Lighthouse, St. Ives, Cornwall. I don't know the exact age of this card, but it asks for a 1d stamp, so it must be from around the 1920s/1930s or so. It is a Real Photograph Postcard, published exclusively for Bathes, The Camera People, St. Ives, Cornwall, numbered 3968 and the card is in very good condition - no creases (other than a little scuffing to some corners) or obvious marks.
