Topps didn't even try to hide that fact. You can see right in the middle is says "Chicago Cubs 1970."
I was trying to identify each of the players shown. Most I could recognize, but not all. My card is a bit fuzzy to try to read the signatures, so I did a search to try to find a clear picture of an original team photo.
What I found surprised me.
This is not the same one that Topps used.
I searched several places for a copy of the version that Topps used, but couldn't find one anywhere. All I could find were copies of the early-season photo. Perhaps the later version is more scarce because attendance dropped as the season wore on and fewer were sold.
The first version did help me identify all of the players shown on the Topps card.
I've got the listing going by columns.
