It is her largest work, and one of her most prominent public commissions, displayed since 1964 in a circular water feature that forms a traffic island at the Headquarters of the United Nations in New York City, outside the United Nations Secretariat Building and the Dag Hammarskjöld Library. It is also the largest artwork cast by the Morris Singer foundry. Copies of a smaller version, Single Form (Memorial) (BH 314), are on public display outside the Johns Hopkins University's Paul H.

Headquarters of the United Nations themselves only, formally, at the request of the Secretary-General. Journalists, when reporting from the complex, often use "United Nations" rather than "New York City" as the identification of their location in recognition of the extraterritoriality status.
