Today we offer you a quick look at some of our war-time posters, published by the U.S. Government Printing Office. The GPO was founded in 1861 and is celebrating its 150 year anniversary this year. It has been located at the same corner of H Street and North Capital Street NW since its founding, and has played an integral part in our nation’s printing history, especially during war time. The posters featured below were printed during the years of United States’ involvement in WWII and emphasized the need for increased production, financial support through the purchase of war bonds, and above all, secrecy. Using lithography, the printers were able to produce posters with hand-drawn lettering and bold colors, despite urgent deadlines, a limited workforce, and a sharp decrease in printing supplies.
