Pinback button promoting Woodrow Wilson for president, 1912. Similar to an Ehrman Mfg. Co. issue, but by a different maker.
With a burgeoning Progressive movement led by former president Theodore Roosevelt threatening to upset the balance of power between the two major parties, backers of New Jersey governor Woodrow Wilson, the Democratic nominee, were quick to tout their candidate's record as a "reformer with results," citing his two years as New Jersey governor, when numerous measures benificial to the common man were signed into law.
This classic pinback presents Wilson as the pragmatic choice of reform-minded voters.
