1) First edition of Walter Camp's seminal 1896 book "Football" is a must-have, as the seminal history of the game by the man who defined it as Yale captain and coach and founder of the NCAA in the late 1800s. VG-EX. Bright red cloth cover is real nice. 2) The "History of the Class of 1907, Yale College" is graced by the noble signature of coaching giant Glenn "Pop" Warner inside the front cover, signed with a flourish "Yours expressly, Pop Warner" in black fountain pen, grading a 7/10. The year is notable, as Warner left Cornell that year to return to Carlisle College -- just as Jim Thorpe arrived. Numerous other Yalie signatures dot the yearbook, which is VG w/spinal damage.
