The New York Times has recently released a collection of ads from the 1960s and they’re crowdsourcing the data for the images. Eventually, other decades will be released. The project is called Madison and if you’re interested in participating, check out the link here to start tagging! You’ll be asked to find or identify ads on the page, tag ads, or transcribe ads.
Another great digital collection of vintage ads is Duke University’s Ad*Access, which contains more than 7,000 ads from the US and Canada between 1911 and 1955. Their digital collection is fully cataloged, so you won’t have to do any of the legwork yourself! You can browse across many different categories including product, company, publication, date, subject, headline, and audience.
