First accretion consists of posters created in the course of the "Willis Wall Demonstration" which took place on September 21, 2016. This spontaneous demonstration was started by student Jazmine McGill, who placed six posters on the exterior of Willis Library. The posters expressed frustration and anger at a series of events in the news involving policy brutality and violence against African Americans. The posters also expressed solidarity with the Black Lives Matter movement. Throughout the day on September 21, 2016 students added their own posters to the wall, and added additional comments to those posters. Additional posters were added to the collection in 2017 following a similar poster demonstration in a different campus location in 2017.
