Richard Artschwager’s unique ovular forms were prevalent in the late 1970s and 1980s. The artist placed them in various locations around New York City, including subway platforms and smokestacks. His intention was to bring the public’s attention to surfaces and structures that usually go unnoticed. Installed throughout the hallways and stairwells of MoMA PS1, they highlight the building’s architecture and reference the way in which visitors move through the space.
