Authenticating real history
Jessa from Bookslut pointed to one of the archives at the Authentic History Center, specifically Treasure Chest’s This Godless Communism produced by the Catholic Guild (and with an introduction by J. Edgar Hoover herself!). This link led to much trepidation about time suckage, as the AHC has some really fascinating stuff. You can peruse WWII military cartoons, comics about atomic energy, a really wrong Howdy Doody cover… a great way to kill a few spare hours! Highly recommended, and adding stuff all the time.
