I ran across this while looking at Baba Yaga images and just had to post it because I think it is a marvelous take on the witch and the chicken feet. Here the costume creators are using two chicken feet to invoke the hut, along with the witch, in one stroke. However, it is entirely appropriate to use chicken feet in a Baba Yaga depiction— it is not uncommon to depict her with a single foot that is a chicken (or even pelican) foot. In fact, a single animal or bird foot often appears on a magical being, and is not a characteristic singular to Baba Yaga.
At any rate, in light of Halloween coming up, I have to say that this is a fabulous costume—and it hints at one of the remaining art projects that I have yet to post 😉
