Aggregated web listings attach several painters' names to this deck, but none of the pages actually read, the publisher's own listing, Goodreads, and Aeclectic Tarot's review, states a name directly, so the claim could not be traced to a citable page and is left unresolved rather than repeated from an aggregation.
What would resolve this The deck's own guidebook, examined directly, which is understood to list contributor credits even where retailer and review pages do not.
