Food for though... how hard would be for someone to plagiarize that exact newspaper and make several copies, and how to verify it is genuine?
That's an interesting question you could ask the publisher, the owner, or the editor of the newspaper. Do their lasers, printing plates or printing presses leave any signs that could be used as fingerprints (either intentionally or innately due to the type of gear used)? Is if it difficult to source the exact type of paper that has been used?
