The work is noted for its emotional disengagement, its intentionally flat dialogue, and a minimalist drawing style inspired by that of Harold Gray's comic strip "Little Orphan Annie". Unusual for comics of the time, it includes a full scholarly apparatus: a foreword, index, bibliography, and end notes. The lengthy, hand-lettered appendix provides insight into Brown's creative process and biases and highlights where he changed historical facts to create a more engaging story, such as incorporating a conspiracy theory not widely accepted by historians. Brown became interested in the issue of property rights while researching the book, which led to a public change in his politics from anarchism to libertarianism.
