An elegant solid wood pantograph wall-mounted bookcase, crafted with an expandable modular system of parallel slats joined by turned cylindrical joints. The lightweight, geometric structure forms a sequence of regular diamonds whose width can be adjusted to fit the available space. The wall mounting points are completed with brass hardware, providing stability and a warm, refined aesthetic. The craftsmanship reveals expert craftsmanship: the surfaces are carefully smoothed, the joints are clean, and the modularity is perfectly calibrated. This bookcase is a rare type of technical-decorative furniture, rooted in the tradition of late 20th-century Italian cabinetmaking. The presence of similar pieces on the market, attributed to master cabinetmakers, makes it particularly interesting for collectors and enthusiasts of wooden design.
