Josef Muller-Brockmann was a Swiss graphic designer and teacher. In the 60's he was appointed the European design consultant to IBM. He was recognized for his simple designs and his clean use of typography. The shapes and colors he used inspired graphic designers in the 21st century.

A key part of his approach involved the use of a typographic grid, which divided space up into a number of consistent horizontal and vertical units.

This poster was made in 1955, I love the background color he has chosen. The black, curved lines varying in height and width pull you from the bottom left to the middle of the page.

Here is a neat video someone did. They animated a poster, Stravinski, Berg, Fortner which was done in 1955. Notice the straight, parallel and perpendicular lines.
