Yes, John Unitas was a Steeler.  A ninth round pick in 1955, Johnny lasted but a couple weeks in training camp -- the Steelers cut him to retain 3rd QB Vic Eaton.   This autograph is interesting in that Unitas' son was annoyingly picky to what he would permit his dad to sign.  The elder Unitas, however, would sign anything ... so a promoter of a show where Johnny was an autograph guest waited until the junior Unitas  temporarily left his father's side (to grab some lunch or something), quickly gave the above helmet to Johnny, and he happily autographed it for me.   I'm not crazy about sons leeching off their father's fame (the young Unitas, the Mantle and Berra boys, and let's not forget Ted Williams' kid), so the score is Jay 1, leeches 0. 

 "Jefferson Street" Joe Gilliam, probably best known as the first African-American to start an NFL game.  Also famous for beginning the 1974 season as the Steelers' starter ahead of Messrs. Bradshaw and Hanratty.  He died unexpectedly, almost immediately after the ceremony celebrating the closing of Three Rivers Stadium in 2000.  It was nice seeing him again there, he looked great.

An *unused* ticket from the USFL Maulers home opener, versus the Birmingham Stallions and Cliff Stoudt!  What idiot missed this opportunity to heave snowballs at Steeler fans' favorite nemesis?

1966 World Series 'Phantom' ticket.  Buccos were close at the end, and printed these tickets in case the Bucs could overtake the Dodgers for the pennant.  Instead, the Pirates were swept three straight by the Giants in the season finale at Forbes, propelling the Giants ahead of the Bucs into second place.  Pirates finished third, 3 games out.  The now useless tickets were surely thrown out, and I probably have a dumpster diver to thank for having this ticket today.

Seldom thought of as a collectible, mint condition credit cards are almost non-existent, due to some apparently genetic urge to destroy them (cut 'em up) at the moment their usefulness expires.  There's a limited market for expired credit cards at this time, but one dealer in Florida estimates the value of the Pirates card above at $150 in mint, unsigned condition.
