The purpose of the research is to investigate the representation or misrepresentation of Pashtun culture through the study of different signs and to inspect that how these signs relate to Pashtun culture by employing semiotics as a tool. To achieve the goal, twelve distinct Pashto film posters that were published during 2011-2017 were selected and categorized under poster design, dressing, props and titles, as these aspects act as signs for depicting cultural insights. The research was guided by the Pierce triadic model for analyzing the type of signs and their interpretation. Various iconic, indexical and symbolic signs were discovered representing the Pashtu cultural traits through certain signs, e.g., traditional dressing, chivalry, male dominance and women segregation, etc. On the other hand, certain extraneous signs were explored, distorting the purity of Pashtun culture by utilizing various signs that were interpreted as referring to violence and vulgarity, which are not acceptable in real Pashtun culture.
