The J. R. Brinkley Platform (1930 write-in campaign advertisement)

A 1930 newspaper-style political advertisement headed 'The J. R. Brinkley Platform', paid for by Brinkley's supporters, including instructions for writing in his name in the Kansas gubernatorial election. Uploaded to Wikimedia Commons as public domain. Used as a case artifact illustrating Brinkley's turn to electoral politics after the loss of his medical license. Identification basis: the Commons record titles it as voting instructions for the 1930 write-in campaign and the visible heading reads 'The J. R. Brinkley Platform'. A dated search on 2026-05-29 of the four supported archives (Wellcome Collection, Library of Congress, BnF/Gallica, and Wikimedia Commons) found no holding-institution record for this 1930 supporters' advertisement beyond its Wikimedia Commons upload; it is recorded here as an accepted residual.
