Hi, my apologies for the late response. Did not see your question right away. The client purchased the shelf directly. I will ask her and respond back.

Hi. My client advised she got the shelf from Pottery Barn. Apparently, the style is no longer available, but there are similar ones at Pottery Barn and West Elm. She shared the Pottery Barn link https://www.potterybarn.com/m/products/vintage-wall-shelf/. Hope this helps.
