F.W de Klerk Autographed book - White Power and the rise and fall of the Naional Party

Up for auction is a hardcover book, White Power & the rise and fall of the National Party (author: Christi van der Westhuizen), signed by the former S.A president and Nobel Peace Prize winner, F.W de Klerk. Mr de Klerk worked closely with the late Mr Nelson Mandela to establish a government of national unity. The book was dedicated personally to me and hence has great sentimental value, but unfortunately needs to be sold. The book is in good condition except there appears a vertical crease in the centre of the first 5 or so pages and on the inside of the dust-jacket (see pics).
