Rare copy of Spalding's Official Football Guide Edited by Walter Camp Containing the New Rules for 1917. This book measures approximately 5" wide by 6.75" tall and contains over 300 pages of pictures and information about various college and high school football teams across the country. Inside, there's mention of Ohio State's invincible All-American Chic Harley as an All-American, an individual photo of him, and him with his teammates in a 1917 team.  In all, the team picture has six Ohio State All-Americans pictured.  Book is completely intact, but the binding is very fragile with crease marks on the cover showing evidence of its heavy use and age.
