Scream promotional poster signed (not authenticated)

This item is a movie poster for the 1996 horror film Scream, presented inside a protective plastic sleeve. The poster features the iconic key art displaying a close-up of a face with wide blue eyes, framed by the main cast members including Drew Barrymore, Neve Campbell, Courteney Cox, and Skeet Ulrich below, along with the large white title text 'SCREAM' at the bottom. The surface of the poster is densely covered in handwritten inscriptions and signatures in various colors of ink, including blue, black, and red marker. Visible text includes quotes such as 'What's your favorite scary movie?', 'You're NOT scared, are you? -Dewey', 'I like to know who I'm looking at...', and 'Clever, Hip And Scary!'. The owner's notes state that this piece is a Scream poster signed by Neve Campbell, David Arquette, Roger Jackson, Matthew Lillard, and Jaime Kennedy; however, this user-supplied attribution is completely unverified, and signatures on memorabilia items require professional in-person authentication before any claims of genuine authorship can be established. The poster displays light surface wear and reflections consistent with being stored inside a plastic protector, but the overall physical print appears clean and intact with legible printed typography and striking high-contrast imagery.

Based on what I can see in the photograph, this item is a promotional movie poster for the 1996 film Scream presented within a protective sleeve, bearing multiple handwritten inscriptions and markers across its surface. Per user submission, the owner identifies this as a Scream poster signed by Neve Campbell, David Arquette, Roger Jackson, Matthew Lillard, and Jaime Kennedy. I cannot verify the authorship of these signatures from a photograph alone, as handwriting and signatures require physical inspection and professional in-person authentication to establish any level of certainty regarding their provenance. The estimate provided here assumes the user-supplied attribution is correct for the sake of market evaluation. In the current marketplace, multi-signed horror memorabilia from iconic 90s slasher films commands moderate collector demand. If the signatures are later determined to be genuine through professional third-party authentication, the piece typically falls into the $300 to $600 range depending on condition, ink fading, and collector interest. However, if the item turns out to be a printed reproduction facsimile signature poster, a mass-produced replica, or if the attribution proves incorrect, the market value would drop significantly, likely limited to the baseline value of a standard unsigned vintage theatrical poster, which is generally under $50 to $100. To fully clarify the status of this piece, one would need physical examination by a recognized autograph authentication expert, alongside any available provenance documentation or chain of custody records. Without these steps, the piece must be treated strictly as an unverified collectable item.
