Caduceus Symbol Pictures Need Help Finding A High Res Picture?

Need help finding a high res picture? - caduceus symbol pictures

I try to find a high-resolution image of the Bar of Asklepios to.

It is the symbol of medicine. He is a staff with a snake wrapped around a stick. Not to be confused with the caduceus rod (I think it is called), which is often confused with the symbol of medicine with two snakes and wings.

I'm trying to make a gift for her, but can not find (the best) pictures of 150x250, which is very grainy. + A 450x450 picture would be perfect.

Thanks
