then displayed in libraries, schools, and museums, and used in parades and events. Historical societies and universities now house historical information about the Ribbon and archival collections of panels. Some of the Ribbons and panels were selected as gallery pieces, and are on display in The Peace Museum in Chicago. Sixty Ribbons were selected by the Smithsonian Institution for its political history collection, and others were given to the United Nations. The Texas Women's University in Denton, Texas hosts a major collection of panels and documentation. Panels were also sent to the National Textile Museum. The Ribbon evolved into The Ribbon International in the late 1980s, and became a United Nations Non Governmental Organization in 1991. Ribbon events can be held for special designated days such as the International Day of Peace (September 21), Earth Day (April 21), special prayer days or other events. Any individual or group can create a panel for a Ribbon, start a Ribbon in their community, or give a panel as a gift to someone who is engaged in promoting peace, environmental causes, or disarmament. New panels continue to be created for display at various environmental and peace events. Ribbons have been given to the New York City Council, Russian President Mikhail Gorbachev, Indian Prime Minister Rajiv Gandhi, and Pope John Paul II. Panels from the Ribbon were displayed at the United Nations Decade for Women international conference in Nairobi in 1985, and others were used by members of Women for a Meaningful Summit at their demonstration at the Geneva Summit (1985). Ribbons were used at peace demonstrations at the Nevada Nuclear Test Site, and the Horse Creek Missile Silo near Cheyenne, Wyoming, and the Great Peace March for Global Nuclear Disarmament in 1986. In 2000, with the help of Betty Bumpers and her group Peace Links, the Ribbon International United Nations Non Governmental Committee gave each U.S. congressional leader a Ribbon for the United Nations International Year for the Culture of Peace, and for the International Decade for the Promotion of a Culture of Peace and Non-Violence for the Children of the World, 2001–2010. Some congressional leaders displayed the Ribbon in their offices. Every year the municipality and city of Lugansk, Ukraine takes part in the Ribbon project.
