A RARE unpublished work by Harry Potter author JK Rowling is being offered for sale for £25,000.
The item 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, offers 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 it, Rowling, above, who is now worth more than 500 million, displays a detailed knowledge of Western astrology which was later to play an important part in her books.
She wrote: "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 chart apparently suggests that the boy will have great literary talent stating "the planet of fantasy and imagination meets a sign frequently associated with bookishness."
Rowling wonders whether his "ability to weave a good yarn" could perhaps bring fame and fortune, before deciding that becoming a film director would better suit his talents.
Apparently wishing for some small slice of fame for herself, Rowling wonders if the boy would perhaps at least mention her in his Oscar acceptance speech "This peculiar woman my mother knows predicted I would be standing before you today … of course, my parents laughed at the time," she wrote.
A spokeswoman for Paul Fraser Collectibles said: "Unpublished illustrations and writings by JK Rowling are incredibly rare and offer a wonderful insight into the creative mind behind Harry Potter.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."
Rowling's love of astrology is evident throughout the books about the boy wizard. Harry himself is a Leo, sharing his birthday with JK Rowling herself, whilst the meticulous worrier Hermione is a Virgo.
Rowling famously wrote the first Potter books in an Edinburgh caf with daughter Jessica at her side. At the time she stayed in a modest home in Edinburgh's Craiglockhart area.
A spokesman for Rowling refused to comment on the sale.
