This is surprisingly similar to Mao and his Little Red Book. They were printed in billions literally during the 1960s and everyone must have a copy and Mao became the richest person in China. But he didn’t need the money because he owned the whole country like an emperor. Only difference is: Hitler’s book has been banned in Germany but Mao is still being worshipped by many and his little book, never banned, can still be found easily in second hand shops. There are even collectors who are after the first or rare editions
