Marko Mäetamm (s 1965) is an Estonian artist, whose retrospective exhibition was the first changing exhibition in the PoCo museum. Pop art is full of artists’ dialogues with the surrounding world and other artists. Marko Mäetamms’ artwork is a new version of his artwork from 30 years ago, therefore artists create homages to their own oeuvre as well. The Teacher artwork from 2024 is depicting a smartphone and it was made during a teachers’ strike earlier this year. On one hand one can ask, if technology can replace human teachers, on other hand one can tell that technology places people in the situation of learning to keep up with the developing (digital) world.
