This is the 1963 revised reprint of the 1953 Edwards Brothers 4th edition of the work. The work contains commentary, graphs, many annotations, and lithographs throughout to help one study the biblical book of “Revelation”. It’s my understanding that the author (Hoyt) was a Christian Science lecturer, so these studies may bend toward the Christian Science views and hermeneutic. This copy is in excellent condition with only some shelf wear on the spine. The cover is slightly bowed (it looks like other books were stored on top of the volume). There are no annotations on the pages.
