OCTOBER 21 TO 24 This month presents a unique chance for practicing printmakers and aficionados of lithography, engraving and their related art forms as Open Studio hosts its large-scale Printopolis symposium (advance registration $265). The event features numerous panel discussions, demonstrations and a group exhibition celebrating the renowned printmaking studio’s 40th anniversary. Outside of the conference itself, more than 40 other Toronto art spaces offer concurrent print-focused showcases, including Angell Gallery, Feheley Fine Arts and Edward Day Gallery.
