There is a really nice collection of Saul Bass posters here from the 1950′s to the 1980s. I am familiar with most of his older work as that is what they teach you about in design school so it was nice to see some of his later work which is really impressive and still timeless. I always wonder when looking at this older work what techniques they used to create their imagery. I know most of it is photographic but I wonder what was used to generate the graphics in the AT&T poster above. Regardless all of it is timeless and artistic work.
