Poster from the film, Indiana Jones and the Kingdom of the Crystal Skull, hand signed by blockbuster screenwriter Dave Koepp.

As a writer, Koepp has worked on such blockbuster Hollywood films as Jurassic Park, Mission Impossible, and Spider-Man. After an uncredited rewrite of the screenplay to Men in Black at the request of Steven Spielberg, he was asked to write the script for Men in Black II, but he declined the offer because he was already working on Spider-Man (see the Spider-Man poster also in this auction!). Koepp had a cameo as the "Unlucky Bastard" in The Lost World: Jurassic Park, in which he was serving as Second Unit Director
