I think by then it was clearly supposed to be Cy. That's evidenced by the fact that the team was changed to Cleveland as Irv never played there. There's no doubt to me that, if nothing else, the card was changed to be a Cy Young card after that change was made.

I think the artwork remaining the same after the team change to Cleveland (and in the case of Sullivan) was merely a case of not wanting to create an entirely new picture. They just passed it off as Irv. Easy to change print/type - not as easy to find a new artist, get a new rendering, etc.
