I've attached 2 '56 Willie Mays cards. The questions I have are:
- Is the variation in color/toning normal for that year?
- Could it be due to the way the card was photographed (flash/no flash) or scanner settings?
- Could it be the difference in one being a white back and one a gray back? Note: I can't tell if one is white or just light gray. Can anyone verify? Pics of back attached as well.

Any other comments are welcome on the comparative condition or potential grade-ability of either card.

Thanks!
