Although the Grand Rapids League of Women Voters was not formally organized until 1921, Grand Rapids women and men enthusiastically joined the effort to promote voter education and registration after a Michigan constitutional amendment passed in 1918 granted women the right to vote. Working through the schools and directly with potential voters, they organized a massive campaign to register voters before the early 1919 primaries. Women received this poster as they registered to vote and proudly displayed their posters in windows across the city.
