As I already own the book, although not in such a nice hardback format, I have no need for another copy. I think it's best that somebody who has never read it is given the opportunity to earn the prize. I got my paperback copy for a mere £9 a couple of years ago from AbeBooks. For a paperback printed in 1966, it's in surprisingly good condition, especially for that price.
But I'll keep an eye on this competition. It'll be fun to watch who the winner is going to be.
And Lou, I think a book is much better than any medal as a prize for this kind of competition. Medals are just coloured pieces of ribbon, but books are treasure troves of knowledge that have so many stories to tell us.
PS. If you change the prize to Willy Coppens' Days on the Wing, first English edition (1932), hardback in good condition with a jacket, I'm in.
