David sez, "The Grand Army of the Republic, an organization of union civil war veterans, held its annual encampment in Louisville in 1895. This 'Sporting Guide' advertises the various houses of ill repute wishing to "entertain" the visitors coming to town for the event."
G.A.R. souvenir sporting guide (Thanks, David!)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
