= Complete series of posters by Pieter Engels (1938-2019) and Simon van Es. "One of the threads running through the work of Pieter Engels is the questioning of image and writing - or rather, the undermining of dogmas, values, evaluations, laws and notions of style (in the narrower sense) in the areas and fringes of contemporary visual art.

Owlgass was initially going to be shaped by means of purely linguistic publications, but eventually it became a combination of text and image, followed by a series of artworks. The strength of Pieter Engels texts often lie in their ironizing, relativizing and perhaps badinage (yet paradoxically: with great seriousness), the visual work is often a combination of these elements with which he continually stimulates the dogmatic in the visual arts. The 8 posters were sent in folded form worldwide by the worldwide wandering gallery of Simon Es (Engels alter ego). All the posters sent were accompanied by a card, which the recipient could return with a comment or request to receive a signed deluxe copy for a fee of one hundred dollars." (www.pieterengels.com).
