For a long time, the majority of researches in design area were restricted to studies of circumstances that had the industrial design as main subject. This way, the design was limited to be understood like products made in a great scale with characteristics related with the contemporary context of capitalism. In this idea, the design was only what was inside of the production of our society. The aesthetic or symbolic anthropology received the mission of investigating the meanings of the drawings in devices made by indians and another`s ethnic groups, it means, to study the symbolic universe of the people that had preceded us in the process of devices production. This people developed technological resources creative and original, however the designers (in a general way), had always ignored the products of this work as a product of design. In this work the understanding about a design product goes beyond the definition commonly disseminated about what the design product may be. The ethnic design appears like a form to rescue the processes, the technology and the understanding of what is produced by ethnic groups that had contributed through this means of production for the formation of the symbolic universe of the materials and products that are part of the daily of the Brazilian population. To understand this universe, to interpret these symbolic constructions is also an important interest of research inside of ethnic design. The objects produced for diverse ethnic groups that compose Brazil are normally observed only as an exotic element that we use as an adornment or as decorative object in our homes. In this way, we ignore its symbolic and technological interest, its understanding with the mystic and of its ancestor`s history. In the text that follows are detached through citations, bibliographical references and interviews that have allowed through the look of a designer to analyze (in a briefing case study) the drawings inserted in the baskets of the indians M`byá Guarani.
