Streamline Moderne Art Deco Cinema — a curved-corner diorama building modeled on 1930s neighborhood movie theaters. Features a rounded façade with horizontal banding, recessed entrance, marquee canopy, poster frames and blade-sign flange. Designed as separate printable parts (marquee, signage, poster frames and base) for easier 3D printing and assembly; walls and details are keyed for clean fit and mounting to a baseboard. Optimized for model-railroad and diorama use and compatible with common scales such as HO (1:87) and O. Includes low-relief ornamentation and clear attachment points for painting and weathering after printing.
