This is a special presentation box set produced in 2005 by Märklin, a long-established German model manufacturer. It's a collector's item containing three luxurious hardcover books themed around the H0, Z, and 1 scales, along with a catalog CD-ROM, all housed in a dedicated case. 【Set Contents】 • Märklin Presentation Book for 2005 × 3 books ・ The Big “little” World of Märklin H0 ・ A Fine Train: Precision in Märklin Z ・ Demonstrate Stature with Märklin 1 • Gesamtprogramm 2005 CD-ROM (Comprehensive Catalog) • Dedicated storage case (with outer box) 【Condition】 The outer box shows slight scratches and minor corner damage, but the overall condition is good. The books themselves show very little sign of use and are in very clean condition. Due to long-term storage, some pages may stick together slightly, but they can be opened carefully without issue. 【Product Overview】 This set is a commemorative document that showcases the technical prowess and aesthetic beauty of Märklin products at the time. It contains a wealth of high-resolution photos, actual vehicle data, and manufacturing background information, making it a valuable resource for display, research, and collection. As it hasn't been opened much, it appears to be in good condition. 【Size】 Outer box: Approximately 33 x 24 x 4cm 【Remarks】 Limited edition with a small distribution even within Germany. Recommended for Märklin collections and as a resource for research on the history of model trains. Please feel free to comment if you have any questions.
