The world is truly in the age of commercials!　Depending on the advertisement, even black can be made to look like white. Shogoro Tobita, who dreams of becoming a cool CM guy, joins "Jun Advertising (Ad) Center" located under the building of the largest company in the industry, "Daidenpoin" (......). The company building is a shambles, the president is a super weirdo, and the only employees are Komako Sugo, a beautiful secretary with a zoo dialect, and a senior monkey named Copy!　How can such a company survive?　A nonsense gag serialized in "Weekly Shōnen Sunday" in 1970!
