A system for the spatial drawing of alphanumeric characters and/or images. The system includes a labelling device designed to form and define the shape of the character based on a product to be suspended in the air that may be of a solid, liquid or gaseous nature. The device has means for dosing and adjusting the product to be suspended, connected to the power unit controlled by the control unit 15 of a personal computer 13. The device also includes means for generating an aerodynamic envelope for the protection of the characters obtained by suspension of the product, for the purpose of holding it stationary in the air for a sufficient length of time for it to be viewed. The system is intended to be used on aircraft, land vehicles or at a fixed point. <IMAGE>
