The whisky marked the 200th anniversary of the Orkney distillery
A "treasure trove" of Highland Park single malt found in Japan has been re-released for sale in the UK.
The limited edition Bicentenary 1977 Vintage was originally launched in 1998 to celebrate the 200th anniversary of the Orkney distillery.
It is said to have become much sought after over the intervening years.
Jason Craig, of Highland Park, said: "We were astounded to discover this rare stock in our previous distributor's warehouses in Japan."
He explained: "This is a very special expression of Highland Park and one which we thought had sold out and been consumed long ago.
"The Japanese have long been recognised as discerning consumers and collectors of single malt whisky and, as a result, a significant proportion made the journey to Tokyo and beyond."
It is said to now fetch £300 and upwards at specialist whisky auctions.
Almost 700 bottles of the Bicentenary 1977 Vintage will be released onto the market.
