Does anyone have a range of impressions of the early Ballantine (white cover, red trim, oval Baynes illustration) impressions? Somewhere between the 24th (March 1970) and the 34th (January 1972) or the perhaps non-existent 35th (February 1972), the text was partially reset. The earlier/original text has 'odd-looking' on page 21, line 8, whereas the reset text has 'old-looking'. Even narrowing down the range of impressions would be useful, if the actual reset impression can't be pinpointed. All help will be very much appreciated!
