A few years after the Revelation Climax! book was released, a group of people from the Children of God (The Family) were at my local shopping mall passing out posters and the one I got is the image below:
On the back is text, which you can read at: http://www.thefamily.org/products/posters.php3?selid=26. Anyway, it was the most cult-like thing I have ever read. Here's an excerpt: "When the Golden Age dawned upon the Earth, the people of the Space King from the new Space City Planet all found themselves thrust into very important positions of leadership and great responsibility! .... When the cruel One-World Government of the World dictator, known as the Beast, rose to power, both Juan and Rosa continued telling others about their King and His soon-to-come Kingdom! Despite the Beast's order that anyone who preached such things should be killed, they boldly defied his forces and delivered tens of thousands of people out of his clutches by giving them the Space King's Words and warnings against the Beast and leading them to believe in and love their Space King!"
Here is just the sort of thing found in the Revelation Climax! book....interpreting your own organization's history as a "fulfillment" of prophecy from Revelation, using group-internal jargon and bizarre concepts. The artwork, tho not as polished as found in the WTS book, is also reminiscent in some ways....
