The fact that these footballs come directly from the collection of NFL legend Jack Lambert makes them valuable enough; add in that they are signed by players from the 1980 and '81 Pro Bowls, and you have a pair of wonderful display pieces. Each is EX-MT with signatures that average 8/10; Jack was in both of these Pro Bowls and these are very special as they were his personal signed balls, as mebmbers of the team signed these for each other. 1) 1980 ball has about 30 signatures with the likes of: Greene, Bethea, Fouts, Campbell, more. 2) '81 ball has 30+ with: Campbell, Guy, Webster, Shell, Fouts, more. Although both balls are very nice, they no longer hold air well; both are separately signed by Lambert with HOF '90 inscription in bold silver marker.
