Since 1998, Michael Bierut's ongoing poster series for the Yale School of Architecture has followed simple design parameters: one standard size, black and white, and all type, using hundreds of different fonts. Designed with Jessica Svendsen, this poster announcing the school's spring 2015 lectures and exhibitions takes inspiration from Yale Architecture's logo, a letter Y in a circle. In this case, each letter on the poster has been built out of circles, over 5,900 in all. 22 x 34, 1-color, offset.
