And people think that 'Flat/minimal design' is something new. Right from when I started designing at grammar school in the late eighties I was influenced by the design of the 1920s to 1950s, especially the travel posters from that time. The limited colour palette of that time (due to printing restrictions) was the making of these posters, once cmyk came in it allowed people to do all sorts of designs; some great, others very very mediocre.
