I purchased these at a Kaminski Auction in Beverly, MA. - so they are from that part of the country.  I can't get over that the 1790 one is 234 years old.  For America, that's OLD.  You get all 8 pieces for your bid.  All are Almanacs except the 1 titled "True Prophecies" - I cannot find a date on it, but it is very old judging from the language and/or spellings used.
