Hehe
A thresh statue would be really cool :p
If you have plenty of money there is a guy that is really good that make custom statues :p And he stream it too :p
There is just a long list of what statues he have to make, so will go some time before you get it.. And his price is 500-800 dollars I think :p But he is making a Rengar Bust mold that he will sell cheaper, think it will be 70 dollars painted :p
