A rare first-edition book of poems by Robert Louis Stevenson signed by the author's mother is being auctioned for charity.
A Child's Garden Of Verses was anonymously handed in to an Oxfam shop in Byres Road, Glasgow, and will be sold to raise funds for the charity.
Stevenson's mother Margaret gave the book, expected to fetch £400-£800, to her niece and nephew as a gift.
She inscribed it: "To my GG Niece and Nephew at Chudleigh with kind love."
Oxfam shop manager John Connolly said: "The sale of this book will raise hundreds of pounds for Oxfam's work to fight poverty around the world.
"For example, £400 would pay for a community library in Malawi.
"This Robert Louis Stevenson book is a wonderful piece of literature as well as a very collectable slice of Scottish history, so I'm hopeful it will attract lots of interest from serious bidders."
A slip of paper inside the book, which was first published in 1885, revealed it came from the library of Dr Adam Watson, who was Stevenson's contemporary at Edinburgh University and his first cousin once removed.
As well as his poetry and travel writing, Edinburgh-born Stevenson's novels Treasure Island, Kidnapped, and Strange Case of Dr Jekyll and Mr Hyde have become some of the most famous stories ever written.
The first edition of A Child's Garden Of Verses will be auctioned at Bonhams, in Edinburgh, on 30 August.
