In the twentieth century it was standard practice in the British comics industry to merge a comic into another one when it declined in sales. Typically, three stories from the cancelled comic would continue for a while in the surviving comic, and both titles would appear on the cover (one in a smaller font than the other) until the title of the cancelled comic was eventually dropped. In this way, two comics were merged with the original "Eagle", "Swift" in 1963 and "Boys' World" in 1964, before the "Eagle" itself came to an end when it was merged with "Lion" in 1969.
