Mysterious Wood Carvings

While visiting Shelburne Farm this past October, I happened upon a stand of wood carvings installed along the path to the barn. They were so striking and unlike anything else at the farm. The raw wood has been left to chip and fade, which adds to their charm and mystery. Take a look.

I have tried to find out about the artist or the origin of the carvings, but no luck. Do any of you out there in the cyber world know where these amazing little totems are from or how they ended up at Shelburne Farms? The only photo I could find of them, besides my own above, is from Josh Bassett Photography (below).
