Jason Scott, of textfiles fame, has scanned in some vintage pulp comics for preservation at the Internet Archive. The Ace Comics Collection so far includes Ernie, Baffling Mysteries, Atomic War, Andy, Western Adventures, and many more. These are from the somewhat rusty pre-golden age of pulp comics between the 1930s and '50s.
Ace Comics were a notorious pulp publisher, not to be confused with David McCay Publishing's Ace Comics title. Ace Comics published horror / detective series for the boys and love story / soft porn for the girls, and never mind justifying the art. In fact, they were an early scapegoat for the moral panic over comics that lead to the Comics Code Authority.
