I am reading up on the history of graphics design and typography and it struck me that non-professional PowerPoint presentation designers today have a similar tool set available to them as the analogue graphic design masters from the 30s to the 60s. Classic fonts, simple shapes, primitive/manual image manipulation tools.

Have a look at this poster by Joseph Muller-Brockmann (I cannot paste it here because of rights): basic fonts, basic shapes. The power of the design is solely created by proportions and shapes.

I stocked up on some more books for design inspiration.
