Framed movie poster in the style of 'Indiana Jones and the Last Crusade' with multiple unverified signatures

This item is a framed illustrative movie poster featuring artwork and billing text for the film 'Indiana Jones and the Last Crusade'. The poster displays Drew Struzan-style artwork with a large central portrait of a character in a fedora, flanked by several supporting characters and horses. The billing block at the bottom includes credits for Paramount Pictures, Lucasfilm Ltd., and various production staff. The user-supplied information states this is a 27x40 inch autographed full cast/crew item; however, this claim is unverified. Physically, the poster is displayed behind a reflective surface in a dark modern frame. It showcases several markings in ink across the surface that are stylistically consistent with signatures of cast members like Harrison Ford, Sean Connery, and Julian Glover, as well as director Steven Spielberg. These ink marks are not verified for authenticity and could represent reprints or later additions. No visible certificate of authenticity is present in the image. There are visible reflections on the glass/acrylic covering, but the paper itself appears to be in good condition without significant fading or tears. The identification of this as a period-correct, cast-signed piece constitutes a hypothesis only, as physical inspection is required to determine if the ink is on top of or part of the print layer.

Based on my examination of the image provided, the item appears to be a framed poster for 'Indiana Jones and the Last Crusade' bearing ink marks consistent with the signatures of various cast and crew members, including those associated with Harrison Ford and Sean Connery. Per the user submission, this is an autographed 27x40 inch full cast/crew item. However, I cannot verify the legitimacy of these signatures or the production period of the poster from a photograph alone. Determination of whether the ink sits on top of the laminate or is part of a printed reproduction would require a physical inspection. The estimate of $4,000 - $7,000 is based on the assumption that the signatures are peer-reviewed and deemed consistent with those of the named individuals. In the current market, high-grade memorabilia from this franchise attracts significant interest; however, value is entirely dependent on the signatures being vetted by a reputable third-party service. Without such verification, the piece would be valued as a decorative reproduction, likely in the $50 - $150 range. To establish a more precise value, an in-person examination to verify ink depth and paper age, along with a review of provenance or a formal certificate from a recognized expert, would be necessary. The current framing appears to be modern and suggests the item has been well-maintained, but I cannot assess potential UV damage or paper acidity through the glass.
