The Boston Public Library has a Flickr set with 351 travel posters from the 1920s, ’30s, and ’40s. And man are they fantastic. I especially love the Union Pacific Streamliner “City of Denver” poster, as well as all of the Austria travel posters.
But that’s not all. They’ve got a slew of other sets as well, such as this one of vintage labels from produce crates.
