No true color variations like you would see with the e98 set. Occasionally, you'll see a card that's normally yellow/gold such as the Gibson or Evers, turn up with color "over-saturation" and the background ends up being a bright orange color.
Here is the e93 Dooin with the upside-down e97 back that someone mentioned previously. A card link this is evidence of a pretty close link between the two sets in my opinion. Also, similar to how there are no duplicate players between the e95 and e96 Philadelphia Caramel sets....there are no duplicate players between e93 and e97.
