With the transport and communications systems advancement, technology has strongly fostered intercultural contact, from which no nation, culture or community can be left out, thus leading to globalization. Thanks to this phenomenon, the Brazilian territory has experienced a significant growth in the flow of foreigners, who come to Brazil for tourism, work or study reasons. Upon landing, these people bring, besides their baggage, different beliefs about the country, which, inevitably, guide their way of thinking and acting in Brazilian territory. Some already widespread stereotypes of our culture promote such practices and lead to a misrepresentation of Brazilian culture, resulting in the idea that here is a country where everything is allowed. This work, therefore, proposes to reflect how these values can be reinforced and interpreted by the foreigners through sign and posters, informative and warning, present in collective spaces, public or private, of Brazilian society. To do so, we take into account the studies of Peterson (2004) and Hofstede (2010), carried out in the scope of Interculturalism; DaMatta (1986, 1997), of Social Anthropology; and Goffman (1980) of Inter- national Sociolinguistics.
