A baker's dozen of legendary gridiron and hardwood greats signed these 3x5" index cards and one signed postcard. Signatures include: Ken Strong, George Halas, Clarke Heinkle (heavily inscribed), Jack Christiansen, Ed Healey, Joe Brennan, Cliff Battles, Dutch Lonborg, Eddie Gottlieb, Marty Friedman, Eddie Nevers, Clifford Wells, Clair Bee and Bruiser Kinard. All were signed from through-the-mail autograph requests, and most inscribed personalizations and notes. Strong wrote: "Good luck with your hobby," Bee wrote: "Good Luck! Hit the books & the hoops!" and others sent thanks for the interest and offered their best wishes. All the cards were certified and encapsulated by PSA/DNA.
