It's a yarn ball wreath! (Child not included.)
It wasn't for sale, but it would be super easy to make. I think I'd use styrofoam balls in different sizes and wrap them with yarn, then wire them together, with or without the glass ornaments.

Can you imagine how much more peaceful the world would be if everyone knitted? Clearly the person who designed this saw the connection.
These would make great holiday art projects to do with kids, or terrific Christmas gifts for knitters/crocheters. I may need to make a quick trip to the craft store.
