 Henceforth each week's cover featured a full-page splash advertising the task which adventurer Simon Test would undertake in a new strip on the inside pages.This strip proved so successful that when the original thirteen-week series was completed (featuring one task each week), Simon Test was given a new series of adventures, extending his hold on the cover indefinitely.He would prove particularly enduring, being one of the few strips to ultimately survive the merger with "Valiant" in 1971.
