These records include:

Hirsch set a new NFL record with 1,495 receiving yards. Despite the fact that the NFL season consisted of only 12 games in 1951, Hirsch's single-season receiving record stood for nearly 20 years, until the merger of the AFL and the NFL.[51]

Hirsch's average of 124.6 receiving yards per game also set a new NFL record. Through the end of the 2015 NFL season, only two players have exceeded this record.[52]

Hirsch also had 17 touchdown receptions in 1951, tying an NFL record set by Don Hutson in 1942. Despite the expansion of the NFL schedule to 16 games, the Hirsch/Hutson mark of 17 touchdown catches lasted until the 1980s, and only four players through the end of the 2015 NFL season have exceeded the mark.[45][53]

On his 17 touchdown catches, Hirsch averaged 51.2 yards, including a 91-yard reception that was the longest of the year in the NFL.[54] For this reason, Bob Oates of the Los Angeles Times wrote that, even in the era of Jerry Rice, Hirsch "remains the greatest long-distance receiving threat of all time."[54]

Hirsch's 66 receptions also led the NFL in 1951 and was the fifth highest total in NFL history to that date.[55]

We got this in a collection of vintage football programs, it's not authenticated but it certainly looks like his signature. Signed in ball point pen.
