You can contact the "St. Maries Gazette Record" newspaper directly by emailing to www.smgazette.com or write snailmail to "610 main Avenue, St. maries, Idaho 83861".
They have all the old newspapers in thier offices and if persuaded with a few kind words may send you a copy.
I would do it for you but I am not planning on traveling to Idaho this year and I live in Agassiz B.C. Canada. Good luck!
