A rare first edition of a novel by a pioneering science fiction writer has been sold for almost £1,000 by a charity shop.
An Antarctic Mystery, by Jules Verne, was written more than a century ago as a response to another novel by legendary author Edgar Allan Poe.
A first English edition of the book was donated to Oxfam in Aberdeen five years ago.
Shop staff decided to auction it online and it sold for £975.
The book, published in 1898 by Sampson Low Marston & Co, tells the story of a journey around the remote Kerguelen Islands in the south Indian Ocean.
It responds to Poe's 1838 novel The Narrative of Arthur Gordon Pym of Nantucket.
Verne is most famous for his novels Around The World In Eighty Days, Journey To The Centre Of The Earth and Twenty Thousand Leagues Under The Sea.
Marion Craigie, the shop manager, said: "We're always looking out for rare items being donated to our shops - including first editions. It's great that this book has raised so much money.
"The sale of this book has also boosted our confidence in the online market. We'd like people in Scotland to know that we've got the same variety of goods to buy online as we do in our shops. I would really encourage people to check it out."
The online shop is an expansion of Oxfam's bookshop at Back Wynd in Aberdeen, and launched in December last year.
