Government Comics on Internet Archive

A search for 'comic book' at the Internet Archive produces pdfs of some US Government comic book giveaways including Mr. Civil Defense Tells About Natural Disasters which has a Li'l Abner cover and Smash-Up at Big Rock with art by Mark Trail's Ed Dodd. There's also a Jack Chick and a Klan comic. I guess there are still some government giveaway comics although the only one coming to mind at the moment is PS Magazine - now with Joe Kubert artwork.
