The book, which belonged to her mother, is inscribed with the words: "Mary Sewell, from her loving child A.S.".
It also bears the printed dedication: "To my dear and honoured mother, whose life, no less than her pen, has been devoted to the welfare of others, this little book is affectionately dedicated."
Black Beauty is among the best selling books in the English language.
