Also, at least two of the WM characters are based on Batman. (Nite Owl I and II. Three or four if you count Rorschach (sp?) and/or Ozymyndias as partly based on Batman.)
Actually, Nite Owl is probably more Blue Beetle (with the legacy and all) considering that Moore's first story involved the Charleton characters. And Rorschach is the Question.
For years I thought that's who this was until I was corrected years ago.
