FIELD: advertising and printing industry, optical systems for observation of three-dimensional objects, in particular, units for labeling and recognition of containers and their content using optical systems for generation and observation of three- dimensional objects. SUBSTANCE: device provides possibility to view three-dimensional alternating color labels or advertisement pictures which are displayed inside or outside of container, for example, various labels, marks, signs, tags and other printed objects with three-dimensional pictures on their surface for various reservoirs and vessels such as bottles or flasks, for example, for bottles of perfume or medicines, glasses, wine-glasses, vases, bowls, ash-trays, various dish and wrapping types, bathes and swimming pools, for articles which carry and/or are made from transparent and non-transparent materials, such as glass, crystal glass, ceramics, polymer materials. Label setter has container which surface is covered with non-transparent layer which provides required image and at least one lens which is located on container surface. Reflecting layer is applied over idle surface of each lens in order to generate image over working surface which is opposite to idle surface of corresponding lens. Lens may be designed as Fresnel lens. EFFECT: increased functional capabilities. 29 cl, 8 dwgl
