Typographic Posters is an excellent site by Andre Felipe that catalogs only graphical or typographical quality poster designs. Any design can apply and then be given access to the site where they can upload their own work.
It’s already shaping up to be an excellent collection with amazing work. Some notable additions include This Studio, David Barath, Michele Genghi, Toko and yours truly.
The poster pictured above is one I’ve been working on but still need to finish.
