Simple answer, The Golden Dawn.
You're doing it again.
Yes, philosophically/historically that's the correct answer. That's where the concepts came from. But artistically, the Vision Quest may just have been designed by someone who had a Thoth deck and looked at the art of the minors - possibly without knowing more about Thoth than that. That's where the pictures in this actual deck came from. And as you have explained, from the point of a view of someone who has studied the philosophies behind the Thoth, the Vision Quest is not Thoth-based (in its philosophy). The pictures, however, are obviously inspired by the Thoth and not the RWS. And yes, both the RWS and Crowley's Thoth are based on the Golden Dawn philosophical concepts. But still, even though there are other Golden Dawn decks, visually the RWS and Crowley's Thoth are the only well-known (among a general tarot public) artistic versions of these concepts. Therefore artistically most contemporary decks, especially the ones without philosophical depth and originality, are based on the artwork of either the RWS or Crowley's Thoth (or the TdM, obviously). That may not make them RWS-decks or Thoth-decks, as you have pointed out, but that's where they got their (lack of) inspiration for the artwork... I think we agree on this?
