The original Three Mouseketeers were published in DC's humor series Funny Stuff, first appearing in Funny Stuff #1. The strip was drawn by Ronald Santi. The series was a loose parody of the classic 1844 Alexander Dumas novel The Three Musketeers. In this case, the lead swordsmice were named Aramouse, Amouse, and Porterhouse, and had various adventures while serving King Looey XIV. Their arch-enemy is Duke Bazook. The series ran in Funny Stuff until early 1948, after which the characters remained unseen for years. The Mouseketeers were revisited in a 1982 Captain Carrot and His Amazing Zoo Crew time-travel storyline in which it's revealed the Mouseketeers are historical figures in Earth-C's version of France during the 17th century.
The second Three Mouseketeers series appeared in a comic title of the same name, which ran from 1956 to 1960 for 26 issues. They were created by Sheldon Mayer, though most of the work was done by Rube Grossman after the first few issues. Though the title was clearly inspired by Alexandre Dumas' novel The Three Musketeers, nothing else about the characters was, with no similarities to the earlier Golden Age series. The stories revolved around three mice, all members of a club. There was the pompous, self-styled leader, Fatsy, who was obese and wore a sailor's uniform similar to Donald Duck's, then Patsy, tall and dim-witted, and last of all Minus, short, dressed in oversized t-shirt and baseball cap with the bill pointing to one side. Of the group, Minus was the most likely to get into trouble though this was usually not of a malicious nature. The mice met at a clubhouse, which was an old tin can with the open mouth covered by a leaf. The mice rarely used this entrance, preferring an underground secret entrance. Their adventures involved dealing with humans, neighborhood cats, and a particularly nasty hawk named Hamilton. The series ended its initial run when DC decided to concentrate on its line of superhero comics. The series did get a revival when it was reprinted for seven issues from 1970 to 1971; later, in the 1980s, Mouseketeers stories were reprinted in digest format along with other classic DC funny animal characters under the Funny Stuff banner.
