While surfing the web in search of flag info, I came across a nicely done site. It covers the state of Wisconsin's Civil War flags and their efforts to preserve them. Some of the really nice nuggets of info are about their manufacture, designs and usage. The pictures are stunning and will surely impress. http://www.wisconsinbattleflags.com/
