I bid on three packs of 'Topps baseball Talk collection cards', the details in the auction were very thin except to say they were rare. Unfortunately the actual sports talk player wasn't included and a further search put it way out of my league.
You can be forgiven for thinking that the cards are regular 1989 Topps however there are some significant differences. Look at the comparison between a regular Topps and the Talk collection card.
Size obviously and smaller tweaks such as the Topps logo and each of the player cards in the set have a facsimile autograph. Turn the card over and you'll notice something completely different.
Unfortunately the cards were not as successful as hoped. The Talk players broke easily and the cards had poor audio, so NFL and NBA versions were shelved indefinitely.
The three sets I purchased included:
1956 World Series Game 5 Yankees vs Dodgers
Ozzie Smith Cardinals
Ron Darling Mets
Pete Incaviglia Rangers
1986 National League Championship Series game 6 Astros vs Mets
Kirby Puckett Twins
Dennis Eckersley Athletics
Gregg Jefferies Mets
