Eagle was a British children’s comic in its own right, published between 1950 and 1969, and then in a relaunched format from 1982 to 1994. It was founded by Marcus Morris, an Anglican vicar from Lancashire.
A perceived lowering of editorial standards preceded plummeting sales, and it was eventually subsumed by its rival, Lion, in 1969, nine issues short of its 1,000th edition. [Wikipedia]
Lion was a weekly British comics periodical published from 23 February 1952 to 18 May 1974, designed to compete with Eagle. It lasted for 1,156 issues. [Wikipedia]
