Tristan,
I've always admired this particular sculpture, it certainly conveys a great sense of movement with the mane flying behind him like that. I believe this model was also manufactured in an all-black version as well as in bronze, and possibly in different sizes, too? The works of Albert Hinrich Hussmann are very collectable, his pieces are quite popular at auction and normally fetch a pretty-penny.
Truly a lovely animal, good choice ...
Best!
