In a recent post to his always interesting column, J.J. Sedelmaier has written an article for Imprint on a fascinating promotional poster series in Chicago in the early 20th century: A True Visionary Gives Chicago A Landmark Branding Campaign Circa 1920-30.
With the help of Dave at Poster Plus, Sedelmaier has accompanied the article with numerous examples of these beautiful posters, most of which are linked to much larger versions.
In sharp contrast to many articles you might see on the web about older posters, these are not only credited to the artists who designed them, but arranged by artist within the context of the article.
Also reprinted on Salon.com as Posters that rival the London Underground.
