Victoria Combalia writes in her essay The Disturbing Objects of Joan Brossa that "certain themes on Brossa's work are easily recognized as 'Brossian': masks, letters of the alphabet, ordinary objects from daily life, playing cards...Perhaps the most important motif - or at the least the most utilized - by Brossa are letters of the alphabet. Brossa works with them as Cezanne did with his apples; he uses them in every way and in all places, as they are for him his dearest motif." In terms of his visual poetry, Combalia states that it "belongs to the long tradition of experimental poetry, in the line that goes from Mallarme to concrete poetry." -- Source of annotation: Marvin or Ruth Sackner.

This is followed by an illustrated section on his own linguistic and compositional techniques involving circular concrete poems, "Rundsheiben." "Walk Talk," a vinyl, floor covering, a portion of which was given to the Sackners by Kriwet is depicted in the book.Kriwet defines his term "Sehtext" as a solution to the problem of visually perceptible literature.
