Built by Wendy Conklin in her home workshop in Austin Texas. Her company is Chair Whimsy. I've pinned the city of Austin.
Matching picture on her Facebook page.
Or go to her facebook page and you will find these chairs in her photo gallery.
She sells her products on Etsy.
Another image of her workshop with the matching floor and matching artwork though different chairs.
Rather certain that I saw these chairs on an online furniture and home furnishing consignment site
