I remember feeling uncomfortable about those old hardback books regarding placing them with folk.
I found them fascinating, personally. LOL. What does that say about me? Oh boy.
They were kind of spooky - the one I really loved was though was Letter to James. It was the favorite of many witnesses I knew. It was the only WT publication that focused on christian love. I read somewhere it was written by a brother who was later disfellowshipped for apostasy.
I look back and wonder what on earth householders must have thought of our Revelation Climax book offering.
Decent ordinary folk, being asked to believe in historic events such as angelic trumpet calls at the release of a new book or new mandate.
