The whole series of "Multiples & Editions" realized by Guillaume Bijl corresponds to his installations of a certain period: posters, small compositions, some "Sorry's", tableaux vivants or projects. Often, these multiples were created as an annex of temporary installations, or with the motivation to help non-profit organizations, or to cover the costs of installations in galleries. After 40 years of practice, the Antwerp Academy was able to trace back about 80 pieces. In February 2021 the Antwerp Academy is exhibiting these multiples & editions and they are being published in a comprehensive book by publishing house Walther & Franz König.The texts of David Vermeiren and Johan Pas put these multiples & editions in context and reflect about all aspects of Guillaume Bijl's oeuvre. Exhibition: Royal Academy of Fine Arts, Antwerp, Belgium (29.01.-14.02.2021).
