We don’t know if this is true, but we have yet to be proven wrong. This concept uses things designers love (pantone chips and small type) to inform them of a speaking event about sustainability and the impact their designs have on the world.
The AIGA normally prints 100+ posters for each event. This design consolidated this excessive amount of posters into one. A green Pantone chip was used to resemble a tree and the poster slowly disappears after each designer tears-off their own copy.
