David---good info, thanks, and congrats on your discovery. Did you see the Lemke article on it. It is on his Blog. From what you know does the variation as you understand it appear only on white/cream back cards. If will have to check my yellow TIGER again ( apologies to Detroit fans, I am a Cardinals guy), which has a white back, to see if it meets your criteria. The Tiger is definitely yellow rather than orange and the card is not otherwise faded as I recall

It is hard to tell from the scan but the one here does appear to have a gray back, and if it is, in it's apparent condition, it may have more value in that category.

It would be odd if the yellow "variation" existed in both gray and white/cream backs since their origin ( grays v whites) seems to have been separate
