To identify your copy of Food Chain Magnate:
The first and second printing have "Orange Juice" on the box instead of "lemonade". This changed in the third printing.
Additionally there are 3 marketing tokens which don't have the infinity symbol on their back. They got corrected in the third printing as well. Last but not least the player aids in english don't have the milestone overview on their back, the german ones have them. This changed in the third printing as well.
