dropoff: I don't recall this book, are we sure it was WT published? or was it a booklet or tract?
It was a WT published pamphlet.
In 1932, right after the Jehovah's Witness religion was founded in 1931, Rutherford published a series of 12 pamphlets (one each month). All 12 can be downloaded here:

The illustrations for all 12 pamphlets are done in the same style
The WT went on to publish many tracts and pamphlets leading up to and during WW2 - they are also available for download at that link*
* "Loyalty", published in 1935, would be an interesting pamphlet to dissect and compare to today's WT writings on loyalty. The 1935 pamphlet focused on the flag salute...I wonder what legal issue they are resisting this time?
