Imagery Mock-up was executed at the end of Morrisseau’s professional relationship with the Pollock Gallery and just as preparations were being made for the landmark Art Gallery of Ontario show, Norval Morrisseau and the Emergence of the Image Makers, which lauded Morrisseau as the trailblazing “imaginative genius” whose visual vocabulary gave rise to a group of First Nations artists that would come to be regarded as the “Woodland School.” It was also in this period that Morrisseau began to visually intertwine traditional Anishinaabe symbols with Eckankar philosophical concepts; the latter of which is represented here in the glowing, yellow eye, with its luminous orange iris and dilated pupil that seems to vibrate on the face of the entranced man.
