London: A rare unpublished work by Harry Potter author JK Rowling is going under the hammer for a whopping 25,000 pounds.
And the piece of work is a hand-drawn, personal horoscope and natal chart, which Rowling gave to the newborn son of a friend at the time she was writing the first Potter book.
The multimillionaire writer, who celebrates her 45th birthday today, had met the parents of the boy at baby classes she attended with her daughter Jessica when she was a penniless single mother in Edinburgh.
The horoscope, dedicated to Jack David Buchanan who was born in 1994, gives a fascinating insight into Rowling``s writing and imagination before she went on to worldwide success.
It comprises 12 loose pages in a plastic folder and is being sold by memorabilia specialists Paul Fraser Collectibles.
The cover illustration depicts the chart``s key astrological symbols of the sun, fishes and a lion in pen, ink, and coloured pencil laid down on bright blue card.
In the horoscope, Rowling, who is now worth more than 500 million pounds, displays a detailed knowledge of Western astrology, which later played an important part in her books.
"Born the cusp of Aquarius and Pisces. He will enjoy school, perhaps be accident-prone, (like all Pisces) could be prone to alcoholism, and (perhaps like us all) may well fall in love with someone totally incompatible,” the Scotsman quoted her as saying.
A spokeswoman for Paul Fraser Collectibles said: "Unpublished illustrations and writings by JK Rowling are incredibly rare and offer a wonderful insight into the creative mind behind Harry Potter.
"It is possible to detect in this short piece some of the characteristics that were shortly to bring Rowling``s prose such extraordinary success; a great and varied sense of humour, flights of fancy underpinned by an internal logic, and of course a mingling of the everyday world with the strange and magical."
