I just stumbled onto this newspaper from Jan 24 1920, at the end of the great war... interesting what the perspective was of "the reds" -crooked NY potiticans, The hight cost of living--troubled mexico-"a trip to the moon" --japan annexing Korea --etc. im not trying to violate any copywrite rules here.
