A bottle of extremely rare whisky is expected to fetch close to £1million when it goes under the hammer next week.

The Macallan Valerio Adami whisky was distilled in 1926 and bottled in 1986. It will be up for auction at Bonhams Whisky Sale in Edinburgh.

Makers Macallan commissioned two world-famous pop artists to design labels for 24 limited edition bottle.

Twelve bottles of The Macallan Valerio Adami 1926 were produced.

One is said to have been destroyed in an earthquake in Japan in 2011, and it is believed that at least one of them has been opened and consumed.

Valerio Adami is an Italian artist famous for painting bold, flat forms outlined in thick, black lines, in a style reminiscent of comic art.
