On April Fools’ Day 1963, the first issue of the Sydney-based satirical journal Oz went on sale. The first print-run of 6000 copies sold within three hours, and a second printing followed. The sixteen pages of black-and-white letterpress sold for 1/3d. Produced on a shoestring budget, it was the work of three young editors (Richard Neville, Martin Sharp, Richard Walsh), all with backgrounds in university student publications. At its height, Oz achieved a circulation of 40,000.
