Insert sets focusing on one dude are nothing new. You can track it back to ’90 Upper Deck’s Reggie Jackson Baseball Heroes set.
I only have the one above, but may have to go online and get the rest of the set.
I hope Panini brings this back. Team Pinnacle has been brought back so maybe these will follow. I would love a Gretzky, Lemieux or Brett Hull insert set. I would love a Peter Bondra set, but I don’t think that is happening.
