This is an old unused colour postcard, probably from around the 1970s/1980s or so of The magnificent Eilean Donan Castle by floodlight. The castle guards the meeting point of Loch Duich, Alsh and Long, Wester Ross. It is by Whiteholme of Dundee, numbered 8746 and the card is in very good condition - no creases or obvious marks (other than a couple of very minor ones), even the corners remain mostly sharp.
