I've counted a total of nine retired Cubs over the years....
2012 - Bill Buckner and Shawon Dunston
2013 - Jody Davis, Leon Durham, Rick Reuschel, and Lee Smith
2014 - no retired Cubs
2015 - Mark Grace and Mark Prior
2016 - no retired Cubs
2017 - no retired Cubs
2018 - Don Kessinger
An earlier incarnation of Archives called Fan Favorites was issued from 2003 - 2005. It too has a bunch of autographs. I haven't chased them since this was out when I was away from collecting. It would be a nearly impossible and overly expensive hunt now.
Cubs in those sets include...
2003 - Ernie Banks, Bill Buckner, Andre Dawson, Leon Durham, Fergie Jenkins, Bill Madlock, Ron Santo, Lee Smith, Bruce Sutter, and Ron Santo
2004 - Fergie Jenkins, Don Kessinger, Ryne Sandberg, Ron Santo, Rick Sutcliffe
2005 - Ernie Banks, Andre Dawson, Shawon Dunston, Ron Santo, Jerome Walton
