National Treasures includes legendary first for John McGraw

He was known as “Little Napoleon” during his 17 seasons as a player that began way back in 1891 and during his 36 seasons as a manager that ended back in 1932, but the memorabilia cards of Baseball Hall of Famer John McGraw found in 2015 Panini National Treasures are a big deal.

Why? They’re unprecedented in hobby history.
