Posters at protests are now created with the hope that they’ll go viral as a meme and amplify the ideas and movement. The recent Hīkoi protest defending the founding treaty of Aotearoa New Zealand was a great example of this transformation. Few posters were mass produced, instead there were tons of different ones each with their own message. https://www.rnz.co.nz/news/te-manu-korihi/537394/signs-of-the-hikoi-more-than-just-words-on-cardboard
