I saw a pretty good looking 'Lience Renewed' at an old bookshop today. It was a hardcover with a dust jacket.I'd say its condition is about 98% perfect, just a tiny bit of wear at the top a bottom of the jacket. The inside says "First published in 1981, this edition published 1981". The front cover looks like this...

and the back cover has a cool picture of Gardner standing in front of a portrait of Ian Fleming.
The price is $22, should I get it, keeping in mind I already have a paperback of the novel ? I have no idea whats good and what isn't in terms of book covers and editions or whatever, can someone help me out ?
