With sales slowly declining, Captain Britain went to black-and-white with issue #24 (23 March 1977) and was cancelled entirely with issue #39 (6 July 1977), though the Captain Britain serial was immediately transferred to Marvel UK's Spider-Man comic, which was then retitled Super Spider-Man & Captain Britain. In 1978, Chris Claremont and John Byrne introduced Captain Britain to an American audience for the first time with Marvel Team-Up #65-66. The Marvel Team-Up story was reprinted as the last six installments of the UK serial, ending with Super Spider-Man & Captain Britain #253. This marked the end of Captain Britain's exploits until March 1979, when Captain Britain appeared with the Black Knight in the "Otherworld Saga" which ran in Hulk Comic. These guest appearances were the first time Captain Britain was written and drawn by British creators.
