U.S. publisher Fiction House was reprinted by both Publications Services Limited, and Superior Publishers Limited (Canada). Issues from Superior tend to have the same numbers as the comics they are reprinting, whilst issues from Publications Services Limited were renumbered to start from issue #1. There is also a single issue known to be published by The American News Company in Canada that is earlier than both the PSL and Superior issues.
Publications Services Limited also reprinted several titles from U.S. publisher St. John, with some alteration in numbering noted.
There is some confusion over who reprinted Prize comics in Canada. It may be Publications Services or it may be Derby. Or they may have reprinted Prize comics at different times.
