I can't find the back scan for these cards but here is Johns Murphy front and back. They all have this back. I realize these should be the scroll 42 but this group missing the color have the factory 30 back. That means John also has a card that there are only 2 examples that I know of. I am sure there is probably a sheet or two of these, so there are probably a few more examples but very few examples.
I am pretty sure there is a Walter Johnson from this group also.
