The projects associated with flight are perhaps the best known and most amazing of all of Leonardo da Vinci's inventions. This slipcase, an edition commemorating the 500th anniversary of the master's death, contains everything needed to build a model of his Flying Machine: 20 sheets of sturdy cardboard pieces plus a book of detailed instructions and an explanatory text full of interesting facts paired with splendid illustrations and remarks, sketches and original drawings by the Renaissance genius that reveal his determination to conquer the sky. The model is easy to assemble, and, when fully unfurled, its beautifully functioning flapping wings measure 60 cm!
