Changing Mad magazine
The great satirical Mad magazine. 'With this issue 24 (July, 1955), Mad switched to a magazine format. The "extremely important message" was "Please buy this magazine!" :D
'Mad is an American humor magazine founded by editor Harvey Kurtzman and publisher William Gaines in 1952. Launched as a comic book before it became a magazine, it was widely imitated and influential, impacting not only satirical media but the entire cultural landscape of the 20th century.'
