Interesting, it seems Topps/Beckett left several collectors wondering what was real on the checklist. I checked cardboard connection as well, there's is a bit more vague but would still lead me to believe Cal had base autos. If you haven't seen them I will take your word, with everything else you have from the set I don't see how they would have gotten past you. Seems odd some players wouldn't have base, I mentioned earlier Biggio doesn't either, just tidal and colors...odd
Every year of Tek since 2014 has done this with random players. Seems like star players don't get a base auto. , just the parallel autos. Troy Tulowitzki has no autographs lower than the disco diffractor /50 print run. Cargo is the same as Tulo, no base auto. but has a disco auto. /50 and on down in rarity. Galarraga too has no base auto., but has all the same autos. as the previous 2 listed. Eddie Butler has a base autograph with no serial #, then all the same ones on down that Tulo, Cargo and Galarraga have.
