Best I can find it is was an insert for a special edition of the Factory set for 2012 Topps. Don't know if any of the cards are different. I didn't see a "factory set" parallel set (there is a parallel "orange" factory set) so I guess the regular base cards from the Factory set are no different than the regular box pack versions. Factory sets are usually only listed separately if there is a difference to the regular set. For example the 1988 Donruss set the front border pattern is reversed on the Factory set vs the regular set.
I collect: Baseball, Football, Hockey, Mostly Vintage pre1980, My Homie teams - Washington/Baltimore Teams Senators (Twins, Rangers), Expos/Nationals, Redskins, Capitals, Bullets/Wizards - HOFers - Non-sport (mostly TV shows and movies).
My Trade List is very much a work in progress
