There's only one I'd buy and that's OUTWITTICISMS.
Jon, your titles remind me of the Little Blue Books published by Emanuel Haldeman-Julius whose business blossomed in the 1920s and 1930s.
After the second world war J. Edgar Hoover took a dim view of the inclusion of certain topics and the publisher was put on the list of enemies.
You can read about Haldeman-Julius here: http://www.haldeman-julius.org/
and the full list of titles at: http://www.haldeman-julius.org/cgi-bin/ ... browse-lbb
The majority of the titles were educational and the books were mostly 5 cents each. You could send off a dollar for twenty titles and include a couple of the more interesting ones (which were probably very popular in the Bible Belt) such as ...
