This is an old unused colour postcard, probably from around the 1960s or so of Sgurr Nan Gillean and the Sligachan Burn, Isle of Skye. It is a Colourmaster International Post Card, by Photo Precision Limited, St. Ives, Huntington, numbered PT36230 and the card is in very good condition - no creases or obvious marks (other than a mark on the reverse), with only slight scuffing to some corners.
