The "Up" balloon was made for the film by Disney-Pixar of the delightful story in which an old man and young boy attach so many toy balloons to a house that it floats away and takes them on many adventures.
The envelope has 540 little inflated balloons on its surface and the spaces between filled with printed images of balloons. Around the basket is an inflated house to complete the picture. This made it necessary to have a highly skilled pilot, because he had to work with a much restricted field of view.
The commissioning manager paid the ultimate complement, because he was shown the photograph of the balloon during its first test and refused to believe that the photograph was genuine!
