Drummer Hoff it tells a cumulative folk song of seven soldiers who build a cannon named "Sultan", and Drummer Hoff, who fires it off, with the book exploding into a blast of colors. The last picture shows the exploded cannon at a future point in time among wildflowers and birds. The illustrations, done in woodcuts, evoke both 1960s psychedelica and Colonial American engravings. In 1969, the book was adapted into an animated 6 minute theatrical short, directed by Gene Deitch.
