Shark Weathervane

This is listed to have a “polished copper finish”. Is this actually made of copper or is it just copper plated?

Per the vendor: All of our Cupolas, including the shark are made of 100% pure copper. The whole piece is copper and not copper plated.

What are the dimensions, I just bought this and realized the size of the item is NOT listed.

Per the features:

Assembled Size: 30" L x 33" H x 6" W; Figure-only: 30" L x 17" H x 6" W
