Print advertisements created by TBWA, Australia, in 2009 for the Sydney International Food Festival, show flags for different countries made out of their traditional foods.
So far the campaign has received a lot of attention from design and advertising sites, as in this analysis by Ads of the World, which includes images of the flags and details as to the designers, or from food websites, as with Kitchn, which focuses on the foods chosen. @Sietar_UK tweeted about it in 2019; clearly they are correct that the campaign should get attention from those interested in intercultural matters, even a decade late. In particular, these flags made of foods should be a good way to get students actively involved in thinking about cultural differences while doing something creative, such as asking them to create flags for additional countries (especially ones to which students have connections), or to research the particular foods chosen and how they are traditionally prepared, and/or what other countries have already adopted them.
