For centuries, when art has featured blood, it has often been displayed in acts of violence, and it is never too sensitive for viewing. Blood has flowed freely across canvases, been carved into sculptures, and immortalized in masterpieces. All types of bloodshed are featured. Except one: period blood. Kotex recognizes periods do not hold us back, but hiding them does. The new campaign “Art’s Missing Period” sets out to rewrite that history by spotlighting art from around the world, including works dating back as far as 35,000 BCE and more contemporary pieces rejected by galleries and removed from public view.
