Murray Warmath autographed book

The Official National Football League Football Encyclopedia by Roger Treat. About nine years ago I was browsing the shelves of an old used bookstore I often frequented on the campus of the University of Minnesota . I was in the sports section, and I came across this book. Being a football and sports history buff, I was intrigued...because I knew it had to be old. I opened it with the intentions of finding the copyright date. Much to my surprise I opened it and there on the inside cover was the signature of Murray Warmath (since verified). He may not be known much outside the state of Minnesota so a little background: After two seasons as coach at Mississippi State, Warmath was named the coach at the University of Minnesota in 1954. He remained there through 1971. In 1960 he won the National Championship and took his team to the Rose Bowl in 1961 and 1962, winning in 1962. He was never affiliated with professional football, so it's a mystery why he had this book, or why it is signed. I guess just a fellow fanatic. As I said, I was on campus when I bought this, and the site of the football stadium (torn down in 1992) where he coached all those years was across the street from the dorm I was living in at the time. I quickly bought the book and walked home, passing by the site where the last National Championship was won. Coach Warmath just recently celebrated his 99th birthday, surrounded by many of his former players. Oh....the copyright said 1952...
