These are all modifications/remixes of public health posters made by the Works Public Administration during the Great Depression. The public-domain originals are available in the Library of Congress. While these posters are colorful, and some of them are mildly humorous, they're not meant to make light of the current dire situation in any way, shape, or form.
They are available as PNG files in both 20"x30" (standard poster size ) and 8.5"x11" (letter size). Contact us for other sizes or formats. Please use them and share them as you see fit.
