La Linea is an Italian animated series created by the Italian cartoonist Osvaldo Cavandoli. The series consists of 90 episodes, each about 2–3 minutes long, which were originally broadcast on the Italian channel RAI between 1971 and 1986. Over the years the series aired in more than 40 countries around the world. All episodes of the series are available today on DVD.

Due to its short duration, it has often been used in many networks as an interstitial program.

The tune played in the background of the series was created by Franco Godi.

Even though the episodes are numbered up to 225, there are, in fact, only 90 La Linea episodes. The 1971 series had 8 episodes, the 1978 series had 56, and the 1986 series had 26.

This ground-breaking two-part series takes us inside two of the most amazing structures in the natural world: our hands and feet.

Hand Model Guru, Sophie Lin, mentors newcomer, Cameron, through the thrilling and neurotic world of hand modeling. After Cameron experiences an uncommonly fast rise to fame, temptations of "Face Acting" put their friendship to the test.
