Persona Entity Sheet
The Persona Entities were not printed with the other Persona cards. They may have been printed on their own sheet, with twenty copies of each card, or more likely they were printed with some Promotional cards, or they may even have been printed with the Piracy Entities or Comedy Club Common & Uncommon Sheet and set aside until the Persona set was finished and released.
Note that the depicted Print Sheets are just example layouts. I don't know what the actual card layout of these sheets were. In fact, the actual layout was likely more randomized to make it easier to pack boosters.
