"Onions and Artifacts" features three photographs of onion skins from a larger set of photos documenting an onion rotting in the final months of 2020. The "visually similar images" feature in Google's reverse image search tool was used to identify three images with Creative Commons licenses that the algorithm believes closely resemble the onion skins. The artifacts from top to bottom: "Head of a Mourner" from The Cleveland Museum of Art photographed by Gary Kirchenbauer; "Venus of Willendorf" from the Museum of Natural History Vienna photographed by Georgi Nemtzov; and "Eastern Woolly Lemur" from Muséum de Toulouse photographed by Didier Descouens.
