Most definitely its the size. Its BIG. Built with an interesting array of materials. Lightweight frame stretched with fabric. Down to the smallest detail a replica of the original, which was actually only 5.7m long (less than 19 ft.) to begin with. Built by the thousands during the Great War, in many colors and configurations. Our model fits large spaces as well as large personalities (of which there is no shortage in this world!). Pair it with propellers, old maps, a pilots desk.
