Awesome to have a copy of this supplement, and a great price! It is true that there are pencil marks, but for the most part, they are only the errata pencilled into the appropriate areas (from the errata sheet on page 68). Still and all, can't be beat for the price. Combine with the original three booklets and you've got everything you need to play D&D the way it was meant to be played. Makes owning Chainmail unnecessary for play.
