Study of the works of Belgian late-modernist painter Raoul De Keyser (1930-2012), particularly his works on canvas made between 1980 and 2012, based on research of the personal papers by the artist held at the "Boekentoren" library. In the long term, this project should result in the publication of a 'catalogue raisonné' (in line with the survey published in 2024 of the paintings from the 1964-1980 era).
