Ahead of this year's 50th anniversary of the National Football League's most unforgettable play, Steelers Hall of Famer Franco Harris' "Immaculate Reception,'' comes the book Immaculate: How the Steelers Saved Pittsburgh. Immaculate weaves together the historical stories of Pittsburgh and its beloved professional football team like the linear strands of DNA—antiparallel, twisting throughout, and irrevocably connected together.
