Nearly 130 years old, this is the first football guide produced by A.G. Spalding & Bros. in 1891. The cover reads "Spalding's Official Football Guide Revised by Walter Camp." There is a vertical crease in the middle, but it is otherwise VG-EX. The pages also have that vertical crease but are otherwise EX-MT. Amazing condition for a booklet that is more than a century old. A year after this guide was put together is considered to be the origin point of professional football.
