Circus animals

I had the idea of looking into circus animals its something I've always been interested in and always hated the idea of making animals perform for our entertainment. They're normally treated horrifically or use to be years ago.  I want to combine the idea of child hood memories not specifically of my own but of children seeing performing animals in moving circus's or at a show or fairground. 

I got the idea from the talk of Belle Vue about them discussing maharaja the Elephant they talked about children queuing to ride and take pictures with the mammal. They talked about how people had such fond memories of all the fun they had there and then we had another talk discussing how the park was shut down due to the conditions in which the animals lived in.
