The book is from 1953 but the theme of polygamous love cults is timeless. He’s probably the most clean-cut cult leader that I’ve ever seen. I guess his other wife is just standing outside the barn, waiting for him to get done whatever he’s going to do. William Vaneer was a pseudonym for Harry Wittington. This book was later republished, in 1964, under Wittington’s name.
This cover was done by Bernard Safran, who did several paperback covers but who is best known for his many paintings and photographs of life in New York.
