Interbrand’s World Changing Speaker Series provides a forum for knowledge sharing with cultural and creative movers at the highest levels of their respective disciplines. We designed Silk screened posters to illustrate six lectures. The posters served two purposes — to announce each lecture, and to be presented as limited edition gifts to each speaker. As a metaphor for the accretion of knowledge, the content for each lecture was screened over the previous lecture and created an evolving artifact.
