Willian Santiago shared a really cool set of illustration for the popular brand of sandals and flip-flops, Havaianas. It was for the father's day campaign in Brazil. What I love about this project and Havaianas is that they are constantly evolving their style. When we started the blog we featured some popular illustrations created for them from designers that became wild successful, mainly because of those projects. So nothing better than sharing Willian's work as well.
