ALL-STORY was one of the earliest pulp magazines, with its first issue coming out in January, 1905. Monthly until 1914, in March of that year it went weekly, and stayed more-or-less at that frequency until it was combined into ARGOSY in the middle of 1920. In May of 1914 it absorbed CAVALIER (begun 1908), a similar Munsey title which at that time also published every week. (For that matter, CAVALIER had absorbed THE SCRAP BOOK, yet another early Munsey title, in 1912.) ALL-STORY, as implied by its name, published a wide variety of stories. Among its most famous (and most expensive to collect) issues are those with the first Mars and Tarzan stories by Edgar Rice Burroughs.
