Model made of birch wood and embossed cardboard with a walnut texture. This affordable gadget is designed for quick assembly without glue or tools, using precisely laser-cut joints. Compact and lightweight, it can be assembled right after purchase and includes a hook to hang it on a car mirror, for example. It’s a mini version of Leonardo da Vinci’s famous armored tank: a domed shell with cannons all around. Though never built, Leonardo’s original 15th-century design became one of the most iconic symbols of his visionary genius. In this micro version, the model blends easy construction with symbolic value, turning it into a small tribute to the Renaissance spirit.
