ROAD 2.0 (Duke University Libraries) provides more than 27,000 images of billboards, 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. The site offers multiple options for searching and browsing (company, product, date, medium, etc.) the collection. Researchers may need to be creative in finding relevant images because subject-based access is limited; although "women" is not used as a subject heading in this collection, try keyword searches for terms such as woman, women, girl, lady, mother, etc. However, this approach will still miss numerous billboards that depict women or that target women as consumers.
Don't miss Duke's other Advertising Collections, such as Ad*Access, AdViews, and the Emergence of Advertising in America, 1850-1920. Women and Advertising Pathfinder is an annotated guide to archival collections at Duke's Hartman Center for Sales, Advertising & Marketing History.
