Pamphlets, fliers, leaflets and books published and printed by the IWW. In contrast to much orthodox Marxist literature, heavy with chapter-and-verse quotations and party-line rhetoric, these IWW publications, many of them written by the self-educated, are full of original ideas, humorous asides, and strong, persuasive writing. The pamphlets and flyers are also rich in graphic content, with bold design and often comic illustrations of union concepts.
