Ryan,
Yes, Powell and Walsh are both 150-350 Series subjects and it's very plausible they were on the same sheet. When I get a chance I'll look at Pat's Plate Scratch research to see if he has either or both players placed on sheets.
Also, the back of the Blue Old Mill Walsh shares multiple little print flaws with other Walsh Old Mills. Some people have said that the Walsh could be re-backed with a blue reprint. That is not the case. I'm not saying I know the Walsh is legit, just that it isn't as simple as a re-back.
