This pinback button bears the name of a Liberty Loan, a financial instrument issued by the United States during the period 1917-1919 to fund its involvement in World War I. With a diameter of approximately 1 inch, it could be affixed to hats, lapels, and other garments as desired by the wearer. Over twenty-one billion dollars was raised through the sale of these bonds to businesses, corporations, and private citizens. It was manufactured by American Art Works from Coshocton, Ohio.
