Bertus (Bert) Griepink is an Amsterdam-based fine artist. He was active in the local comics and cartoon movement of the 1970s, after completing his studies. His titleless comics dealt with the social and political affairs of the time and appeared in De Metropool (1971), Amsterdams Weekblad (1972-1973), Tabk-wonen (1973), Tand des Tijds (1976-1977) and Kraak Krant (1977).
He got a regular weekly spot in De Nieuwe Linie in 1977. An entire run of the PSP magazine Radikaal was confiscated and destroyed in September 1977 due to Griepink's frontpage illustration. He printed silkscreens through his own printing firm De Vrije Zeefdrukker, and made many flyers, prints and posters for local protest and squatter's movements like Aktiegroep Nieuwmarkt.
Besides his political illustrations and cartoons for magazines and newspapers, Griepink also made free work. He developed his realistic painting, through total abstraction, to eventually settle in a figurative style. He has made murals and commissions, among others in the Nieuwmarkt metro station, and has exhibited his work throughout Amsterdam on many occasions. He alternates living in Amsterdam with Nyer, France. In France, he is represented by the Gallery de l'Olympe in Perpignan.
