At the end of the credits!!

The following statement is near the very end of the credits:
"This film was proudly made by hardworking children in factories."

I found that very... odd. It's the first time I've ever noticed any notice like that in a movie. I've tried finding a picture of that quote in the film, but can't seem to find anything on it on the web. Anyone else notice it too and might be able to throw up a link to more information?
