Tarzan of the Apes
One of the most significant events in pulp-fiction history happened in the October 1912 All-Story which published Tarzan of the Apes by Edgar Rice Burroughs. This issue remains the single most collectable of all the pulp magazines. In 2006, a copy was sold for $59,750 at auction.
