"The Finished Mystery," by Clayton J. Woodworth and George Fisher (1917). This was published as Volume 7 of Studies in the Scriptures and advertised as the posthumous work of Charles Taze Russell. This is a text version of the first printing and also contains pictures that were circulated in the Karatol edition. Later printings contain significant changes. Publication of this book was authorized by J.F. Rutherford, president of the Watchtower Society. Rutherford later gave the group the name Jehovah's Witnesses in 1931.
