ROAD 2.0: digital collection from Duke University Libraries (USA)

More than 27,000 images of billboards and other outdoor advertisements have been digitized and made available online by Duke University Libraries. The new digital collection, ROAD 2.0, brings together a vast collection of historical advertising images from the John W. Hartman Center for Sales, Marketing & Advertising History, part of Duke's Special Collections Library. The images, most of them taken between the 1930s and 1980s, include not only billboards but also wall paintings, electric "spectaculars" (such as the neon signs New York's Times Square), bus shelters, taxi displays, and behind-the-scenes shots of outdoor ads under construction and sign painters at work
