#histmed #twitterstorians: I& #39;m looking for a good image from the 1918 flu focused on avoiding infection. Photos of people in masks, a US government poster, etc. Any ideas?

Probably won& #39;t be able to use it for this, but my favorite image from your kind suggestions so far (source: National Archives).
