This is a very old unused black and white/sepia postcard of Jersey, St. Aubins & Beaumont. I don't know the exact age of this card, but it looks like it is from the very early 1900s. It is a Real Photo Post Card, published by Photochrom Co Ltd, Graphic Works, Tunbridge Wells, numbered 41591 and the card is in very good condition - no creases or obvious marks (other than some on the reverse), with only very slight scuffing to some corners.
