This is not an official valuation and should not be used for insurance, sale, tax, estate, legal, or lending purposes — or any decision requiring a certified appraisal.

This item is a children's book titled "Gutta i trehuset med 13 etasjer," which is the Norwegian translation of "The 13-Storey Treehouse" by Andy Griffiths and Terry Denton. The book features a vibrant red hardcover, suggesting durability for its target audience. The front cover design is highly graphic and engaging, displaying caricatured illustrations of various characters, including two main boys, lively creatures, and elements depicting the fantastical nature of the 'treehouse.' The title is prominently displayed in a playful, somewhat blocky font, with "Gutta i TREHUSET" in a larger, dark yellow, and "med 13 etasjer" in a slightly smaller, white font. The authors' names, "ANDY GRIFFITHS TERRY DENTON," are printed in a smaller, lighter font at the top. Near the bottom right, there's a small yellow arrow icon with text, likely indicating a series or special edition detail, though the text is too small to decipher clearly. The book appears to be in good condition with no visible significant wear, tears, or damage to the cover, suggesting it has been well-maintained or is relatively new. The physical dimensions appear to be standard for a hardcover children's chapter book, likely around 8-9 inches in height. It is a mass-produced item characteristic of contemporary children's literature, designed to be visually appealing and durable for young readers. The illustrations are vivid and contribute to the inviting nature of the cover, indicative of the whimsical content within.

I have examined the provided image of "Gutta i trehuset med 13 etasjer," the Norwegian translation of "The 13-Storey Treehouse" by Andy Griffiths and Terry Denton. Visually, the book appears to be in good to very good condition, showing no significant wear, tears, or damage to its vibrant red hardcover. The graphic cover art, characteristic of the series, is intact and appealing. Its physical dimensions seem standard for a children's hardcover book.
This is a mass-produced, contemporary children's book. The "The Treehouse Series" by Griffiths and Denton is highly popular globally, and translations are widely available. Market conditions for contemporary children's books, even popular ones, generally show modest values unless it is a signed first edition, a true first printing, or has some other unique distinguishing characteristic not discernible from the image. Comparables available on secondary markets for standard editions of this series, including translated versions, typically fall into the low single-digit to low double-digit dollar range.
Demand for this title in Norway would be consistent, but given its mass-market nature, rarity is extremely low. Factors impacting value negatively include its status as a widely available contemporary item and a translated edition. Positive factors are its good condition and continued popularity among its target audience.
My appraisal is limited by the visual information available. I cannot definitively assess authenticity as a truly 'first' edition or printing without examining copyright pages, print runs, and ISBN. An in-person examination would allow me to verify the precise condition more thoroughly, check for any internal markings, and confirm the specific edition details (e.g., first Norwegian print). Provenance documentation, such as purchase receipts or author signatures, would be necessary to identify any unique collectibility that could significantly elevate its value beyond a standard used copy.
