This poster was used during 1940s to accommodate "Thai Cultural Revolution" in order to make Thailand more "civilized" as it was the national project of Field Marshal Phibun Sonkhram, the prime minister. As Phibun aimed to modernize and made Thai society progressive and civilized, he tried to change Thai people's way of life in every aspect in order to make it similar to Western countries, who were considered to be "progressed" and "civilized". Therefore, this poster became an evidence to show how the government during that time was trying to reformat people's dress code as the first step of becoming advanced. The poster's heading reads "Thai Culture", while there are two charts addressing what should and should not be worn.
The first column "Don't" shows Thai traditional dress codes as most of the citizens, especially men will be bare chest and wearing traditional cloth or "jong-kra-ben", while the other column "Do" shows Western dress code as men must wear shirt and a trouser, and women will wear a shirt and a skirt. The picture is interesting in a way that it conspicuously shows how the government tries to obtruding this new fashion to the citizens by using the phrase "Thai Culture" as the heading, which makes it automatically indisputable and sounded like it is already been accepted by everyone in the society. In this way, it also reveals how authoritative and powerful the government was during that time. Also, it unveils how Western cultures were being praised highly and regarded as prime example of the country. Moreover, it also tells the image of a good and civilized citizen should be during that time as it becomes the foundation of Western fashion of Thai society.
