Little Einsteins is a children's television show that aired on Playhouse Disney (now Disney Junior) that was created by Disney and The Baby Einstein Company. But long before its debut, an early preview of the show appeared on the previews for the Baby Einstein DVDs Baby Mozart, Neighborhood Animals and possibly Baby Beethoven.
This is said to be extremely rare to find and a video of this has not surfaced, though footage once appeared on a defunct Disney wiki page. The photos were taken by user Dinojungle but later removed by the Disney wiki because of plagiarism.
The early preview has a stay tuned bumper with Leo, Annie, Quincy and June sitting in rocket.
The promo itself has rocket flying around places and the Little Einsteins at the playground swinging on swings and singing.
The footage was uploaded to YouTube in 2015 with the names Little Einsteins Promo and Extremely Rare Little Einsteins Early Preview.
