The series premiered in 1940.

The title characters are brothers living together in a brick house in the deep woods. They are Practical Pig, who is serious and hardworking, and the thoughtless happy-go-lucky Fifer and Fiddler whose names refer to their interests in playing music.
The brothers are eternally stalked by Big Bad Wolf, who longs to eat them for dinner, but his dastardly efforts are countered by his righteous son Li'l Bad Wolf (and sometimes by Brer Bear). They manage to thwart Big Bad Wolf's endless hunting schemes.

The stories were/are written by an overwhelming number of artists. Examples: Carl von Buettner (1905-1965), Carl Robert Fallberg (1915-1996), Jim Kenner (ca.1920-), Jan Kruse (1946-), Evert Geradts (1943-), Joel Katz (1945-).
