Satire: You Can't Always Get What You Want

I saw this making the rounds the other day and got a kick out is - as has any other zoo professional who has tried doing anything for their animals while balancing the input and influences of a half-dozen other entities at their institution.  The picture appears to be credited to Alan Sharples of Atlanta Zoo (which makes me suspect it must be pretty old - it's been renamed "Zoo Atlanta" for decades).  If this is not correct, please let me know so I can give credit where it's due!
