Cunning Stunts (Metallica) Easter Egg - Director's Name Written in Concert

In video 1, as the band plays the song 'One' and the guitarist is about to do the final solo about 5 minutes into the song, the camera crosses to the soloist (from the crowd's point of view). A person in the crowd holds up what seems to be a silhouette of a book or poster of some kind. Its only short but if you pause and advance to that particular frame, you'll notice some writing written on the silhouette. It says 'Wayne Isham' which I later discovered out was the director's name which has been added on editing. The funny thing is that you never notice it if you're just watching because it's only there for one frame!
