The Little Red Book: 5 Billion of Them
During China's Great Cultural Revolution from 1966 to 1976, the famous "Little Red Book", officially known as Quotations of Chairman Mao Zedong, was a must-have item for the Chinese.
It is estimated that during those years altogether 5 billion copies of
the collected Mao sayings were printed, which came in 500 different
editions and 50 languages. Back then, the total world population was
about 3 billion. So there was more than one and half a copy of the
little red book for every inhabitant on earth.
Now, one can hardly find one copy anywhere.
