A 1st US Trade edition and first impression copy of both Jurassic Park and The Lost World by Michael Crichton in excellent condition all round. The books are very good indeed with no rips, tears, inscriptions, missing pages etc. There is no real age tone to either book and the pages remain bright and clean (see pics). The dust jackets are excellent with no real shelf wear or marks and only a slight fade to the spine of Lost World. Both are protected in a plastic collectors sleeve (see pics). 

Overall, an excellent set of one of the most famous series in the world.
