Nice one, Gary! $956 is impressive and I'd suggest a bit on the low side even, given that it is Ruth and it is rare.
Lots of good info has already been provided. I'd just add this image of Ruth-Johnson-Sisler-Coveleskie. The card came out of a new-to-the-Hobby Universal Surprise box that also included a four-panel nonsport card, so in conjunction with the prior box discoveries, I think the origin question for the issue is resolved for sure:
Now, if the artwork from the 4 panel cards were used to make the 6 panel head shots--which certainly looks to be the case for Ruth--then we might have some nice cards awaiting discovery down the line.
