robert aHi there.
This one's been discussed before. It's a good topic. Search for it.
I believe it's simply because the caramels feature stars of the day that had been around longer than WJ.
Some of the others might know a lot better, but it could be possible that the "pool" of photos used for many of the players included in the sets (many are the same players used across several caramel sets) did not include johnson.
Nice topic.
