J,
Thank you for researching this really important sculpture and presenting us with such an informative essay. I have always wanted to know more about it and I definitely think it should be included in the time capsule. 
Valerie (who commented before me)  has already asked my question so I was wondering if you uncovered any information about the human models that may have been used for the human figures in the piece. Was it one man that was used as a model or four different men?
