How do you identify a building without ruining the look of it? Schools, businesses, churches all need signage.The challenge is to do it in a way that is consistent with the building's design ethic. In the East Village of Manhattan, Cooper Union's newest structure required something sleek and modern. Shiny silver letters wrap around the overhanging edge of the entrance. They blend in with the matte silver skin but are different enough in texture to be readable from any angle. It's an ingenious solution that is completely in character. Would you expect any less from a school that focuses on art and design?
