In many cultures of the world, the egg represents life, because from the egg the life starts. The egg on the pedestal represents balance in life; if u make wrong choices, you fall, like the egg when you put it wrong on the pedestal. At the same time, if you make the right choices, you will be stable, like when you put the egg correctly on the pedestal. We work with lots of museums, and we can personalize the eggs, like the one shown above. You give us the subject and we can adapt it on the egg. 
Note: every egg has its own box and pedestal.
