When one speaks of retro art, images of art styles derived from advertising and propaganda posters from 1930s to 1960s usually flood the mind. The simple graphics made from oil paints reflect the less advanced technology of that time. This period is also a time of significant turbulence in our modern history, when major events such as the rise of communism and World Wars were taking ground. It is then not surprising that many posters serve as propaganda tools for the ruling governments. These propaganda images eventually contributed to the development of different retro art styles.
