For many decades, Awake carried a statement on its inside cover to the effect that "The Generation that was old enough to understand the beginning of the Time of The End in 1914 would still be around to see the End of the System". (It wasn't quite worded exactly like that - my memory is no longer that good!- but that was the substance of the message they put over).
Then ....... after a certain year, which in the Gregorian Calendar is numbered AD 1975, that statement was modified - just a little!
It now read to the effect that "The Generation that saw the beginning of the Time of the End would still be around to see its end".
I understand that this statement was again modified in the mid-1990s, although others will have to tell us exactly how, as I had parted company with them by that time.
Other than that, I am not aware of any 20th Century type remarks in Awake that were subsequently reprinted.
