This is an old unused colour postcard of Shetland Isles. I don’t know the exact age of this card, but it is likely to be from the 1970s/1980s or so – and the date 1984 has been added to the reverse. It is a "Hail Caledonia" Post Card, by Whiteholme (Publishers) Ltd, Dundee, numbered 6414 and someone has added the following to the reverse – 1984, Agnesville, Sandness, W. Mainland, Shetland Isles. The card is in very good condition – no creases (other than a couple of very minor scuffs) or obvious marks, with only very slight scuffing to some corners.
