This is a framed, multi-color screen-printed poster for the High Sierra Music Festival, which text on the piece indicates took place on July 2, 3, 4, 5, 2009, in Quincy, CA. The central illustration features a stylized natural scene with a large dark blue bird (resembling a Steller's Jay) perched in a tree surrounded by smaller birds, flowers, and forest elements under a swirling blue and white sky. The owner attributes this specifically to the 2009 festival, which is consistent with the printed date. The bottom margin contains several printed and handwritten markings: it is explicitly credited as "artwork by Marq Spusta" and "printed at Monolith Press." On the bottom left, the piece is hand-numbered "12/150," suggesting a limited edition run. To the right, there is a pencil signature that appears to be Marq Spusta's. The poster is presented in a simple wooden frame and appears to be in good condition, though there is a noticeable vertical crease or undulation in the paper on the right side. The stylistic hallmarks—dense, whimsical nature-themed line work and a specific muted color palette—are highly consistent with Marq Spusta’s known body of work.

Based on the provided imagery, I have evaluated this screen-printed poster, which the owner identifies as a 2009 High Sierra Music Festival limited edition by Marq Spusta. From what I can see, the piece displays the whimsical, dense line work and organic color palette characteristic of the artist's style. The hand-numbering '12/150' and the pencil signature in the lower margin suggest it is from a small limited run, which generally increases desirability among concert art collectors. However, I cannot verify the authenticity of the signature or the printing process from a photo alone; a physical inspection would be required to confirm the paper stock and the presence of genuine screen-printed ink layers. The value is significantly influenced by the condition; while the colors appear vibrant, I noticed a visible vertical crease or undulation on the right side of the paper. Such condition issues typically detract from the value of collectible posters, which collectors prefer in mint state. This estimate assumes the attribution provided by the owner is correct and the piece is an original 2009 printing. In the current market, comparable limited-edition festival posters by sought-after illustrators frequently see high demand in this price range. To confirm this value, I would recommend an in-person authentication and an assessment of the mounting methods used in the frame, as acidic materials can damage the paper over time. If this were determined to be a later digital reproduction or an unauthorized copy, the value would likely drop to a decorative level, typically under $50.
