Cravan Mystery Man of the Twentieth Century

This is a true story about the most interesting person you've never heard of: Arthur Cravan, major figure in pre-WWI cutting-edge art circles, was among the greatest mysterious figures of the Twentieth Century. A self-confessed thief, forger, and con-artist, he used a roster of assumed names and false identities. He was known, at various times, as a novelist, poet, painter, art critic, lecturer, publisher, and the lightweight boxing champion of France.
Always a rebellious, restless spirit, this dedicated rule-breaker was a political radical whose friendship with Leon Trotsky earned him the surveillance of the U. S. government-even through his immigration to Mexico with his wife, the poet Mina Loy. In 1918, at the age of thirty-one, the fascinating physical giant vanished without a trace, and-despite several supposed sightings over the years-was never seen again.
Is it possible that he became the mysterious, reclusive novelist B. Traven, who wrote The Treasure of the Sierra Madre?
