For the Nifty-50 project, 50 top creative designers from around the world were selected to design one poster each around the topic of money. As you can see in the previews in this post, this theme can be interpreted in many ways, you should check out their dedicated website to see more.
Every poster was printed as a super-limited edition of… one. The posters are sold by the project organizers, Socio Design, and the money goes to charity.
