The card is an instruction sheet for assembling the panel from pages in the book; the loose sheet is an errata sheet.In the introduction to Carnival Panel Two, McCaffery comments on Panel One. "Carnival is planned as a multi-panel language environment, constructed largely on the typewriter and designed ultimately to put the reader, as perceptual participant, within the center of his language.The roots of Carnival go beyond concretism (specifically that particular branch of concrete poetry termed the `typestract' or abstract typewriter art) to labyrinth and mandala, and all related archetypal forms that emphasize the use of the visual qualities in language to defend a sacred centre. Pond's vorticism also forms part of the grid of influences, and on one level at least, Carnival can be seen as an attempt to abstract, concretize and expand Pound's concept of the image as the circular pull of an intellectual and emotional energy. Above all it is a structure of strategic counter?communication designed to draw a reader inward to a locus where text surrounds her. Language units are placed in visible conflict, in patterns of defective messages, creating a semantic texture by shaping an interference within the clear line of statement." -- Source of annotation: Marvin or Ruth Sackner.
