Is this how Buster Keaton got started?

All IMDB says is that she was “a child celebrity known for having a perfect sense of balance,” and was the daughter of Sid Goldy, who it identifies only as the father of Helen Sue Goldy.  Hmm….

The piece was included in a 1946 Pete Smith behind-the-scenes one-reeler, Studio Visit, which was released in conjunction with the Ethel Waters — Lena Horne musical, Cabin in the Sky.  The narrator claims they’re practicing their act for a movie, but the piece apparently never made it into any other film. 

That’s all I can find on this.  Anyone?
