Thunderbirds Extra

A one-shot special from City Magazines, Thunderbirds Extra (1966) expanded on the world of the classic Supermarionation series with a single issue of original comic-strip adventures. Featuring the craft and crew of International Rescue, this British publication offered fans a print-only glimpse of the Tracy family's high-tech rescues during the height of the show's original run. While brief, it stands as a period piece tie-in from the peak of 1960s TV-inspired comics.
