During the first 6 seasons of Sesame Street, each episode began with an animated sequence that ended with the show's episode number.
International co-productions that premiered during the 70s (with the exception of Sesamstraat in the Netherlands), including Plaza Sésamo, Sesamstrasse, and Vila Sésamo used these animated sequences during their early years. However Sesamstrasse continued to use these segments long into the 1990s, as well as creating their own opening animation sequences. The particular segments re-used from the original American version also had different soundtracks and redrawn colors. Those segments were phased out after 1995, when Sesamstrasse stopped airing repeats of the 80s episodes, and the number sequences were eventually discontinued after 2000.
The following is a listing of known animated sequences.
A unicorn and abstract man form the words "SESAME STREET," which is then placed on an arch. The episode number appears below as the two enter through the arch. The animation was done by Jim Henson. (First: Episode 0001)
An egg cracks open, causing a bird to pop out, holding a box. A smaller bird holding an upside-down hat pops out of the box. From the hat, a pelican's head emerges and he opens his beak, revealing a little bird who sings some musical notes. The notes dissolve into the words "Sesame Street" and then fade into the episode number. (First: Episode 0131)
