UPDATE, 5:45 p.m.: I spoke with a representative for PlumStruck who said that they don't actually produce the Banksy prints, but get them through yet another third-party supplier. When I asked the PlumStruck rep who their supplier was, she told me she "didn't have the spelling" of their name, but that phonetically it sounds like "Kroto Inc" (a cursory Google search doesn't turn much up). I've also asked the PR agency that represents Banksy to weigh in on the matter.
UPDATE 7:15 p.m.: Here's a full statement from a spokesperson at Walmart:
These items are sold through our Marketplace third-party sellers Wayfair and PlumStruck. We’ve taken action to disable the one item in question by Callo, and it will be unpublished later tonight around midnight PT.
We will also instruct Wayfair and Plumstruck to review their artwork to ensure the descriptions are accurate. They’ve provided great products and experiences to our customers and are contracted to comply with product copyright, safety, testing and certification requirements. We’ll work closely with them on the review.
