Minnie Corum wrote a memoir titled "I Licked a Stamp" that detailed her life as postmistress in Encampment, Wyoming, from 1918 to 1946.
She was not only a longtime postmistress, she was a successful problem-solver.
One snowy Christmas the mail was delayed for four days and no one received their Christmas packages.
Once the mail arrived, Corum quickly organized a project to deliver all the mail since there were too many packages to fit in the post office.
She called everyone around town, and they had a big party delivering mail straight from the mail sacks to the gathered crowd.
It took only four hours to unload four days' worth of mail.
