The National Underground Railroad Freedom Center (Freedom Center) in Cincinnati, Ohio, is requesting proposals for the design of Invisible: Slavery Today, an exhibition about modern forms of slavery. The Freedom Center created an initial version of the exhibition in 2007. The exhibits content is largely still current and will require only minor upgrades. This RFP is for a complete re-design of the exhibitions displays, lighting, audio-visual components and related materials. Our goal is to open the refurbished exhibition at the Freedom Center by mid-year 2010 and, following a nine to 12 month showing, offer the exhibition for rental to venues in the U.S. and overseas.
