Giovanni Pintori was an Italian graphic designer and painter. He worked in the advertising department of Olivetti typewriters and became the art director from 1950 t0 1967, well known for many of the advertisements and posters of the company. His style is minimalist employing bold colors and geometric shapes. On the website, Giovanni Pintori Research, he is quoted as follows:

“I have always believed in the strength of simple ideas and the demand for clear, immediate language that is accessible to everyone. This doesn’t mean that the language of graphics is downgraded to the most common taste. Just the opposite: it means that the language intends to improve average tastes. This is a goal I set a long time ago.”
