Good Fences Make Good Neighbors

Nearly a year ago, artist Ai Weiwei's project, “Good Fences Make Good Neighbors,” commissioned by the Public Art Fund, covered New York City with installations and banners in reference to the current international refugee crisis. Though the works are no longer on display, their message remains even more pressing. In commemoration of World Refugee Day on June 20, the Public Art Fund and eBay for Charity put Ai’s project back into public reach with the sale of limited-edition original portrait banners drawn from those made by the artist (h/t Surface). There are six banners in all, and sales benefit USA for the United Nations High Commissioner for Refugees (UNHCR), the International Rescue Committee (IRC), and the Fund’s mission to promote accessible art.
How much are they, and how do I get one?
