This is a package from a swiss brand called Geigy. It’s made in the 60s. What technique has been used to create the ant would you say?
It is very likely made using silkscreen or lithography.
Since these designs seem to have been made using stencils cut out of paper, I think silk screen printing would have been the more practical approach. The grid-like outlines of the shapes also corroborate this type of printing. (Of course, consequential prints were probably made using offset printing.)
I believe this is a photograph of a prototype for this box of the ant-killer Neocid, since even the folding lines seem to have been printed.
The source of your image can be seen here: 'Graphic Design Manual, Principles and Practice', by Armin Hofmann.
He was part of a team of designers who were employed by the Swiss pharmaceutical company Geigy in the 1960s to advertise their products to doctors and in medical journals (as direct advertising to the public was prohibited).
Hence the artist of this particular packaging is an unknown student (see image below).

The style is called International Typographic Style, which is also known as Swiss Style.
