How can you tell if a classic Batman comic book cover is a reprint or an original?

Several factors help determine if a cover is original. The cover date and issue number are key. Compare these details with known publication information for the comic. Check for any clues of restoration or tampering. Examining the paper quality, printing techniques (ink quality, dot patterns), and advertisements within the comic can also offer clues. Consult comic book price guides and expert opinions to confirm its authenticity.
