The following series have the checklist included as separate card in each pack. The backs of the checklists form a nine card puzzle (example), so there are nine different checklists for these series, depending on which puzzle piece they have on the back.
Checklist Terminology: Because some of the puzzles are horizontal (e.g. 1st) and some are vertical (e.g. 11th) there has been some confusion about checklist terminology.
