Yes it was full of the false doctrines the WTS concocted to help sell it to the public, just like most other pieces of literature put out by the WTS.
People who are JWS are just the WTS's own self designed public sales representatives.
The more "time" you spend out selling/distributing these pieces of literature made by the WTS the more they are showing loyalty and devotion to Jehovah and elevating their righteousness in his eyes.
