Sometimes the Gray backs scan as a lighter colored back, but there is a noticeable difference. Also, on at least the cream backs, the smudge or masking of the Tiger begins to drift up Frank's throat. I tried to make a close up of the area in question. This Tiger has some of the red, but you can see the red is beginning to splatter, as well as the streak of green often found with the Pale yellow near his throat. Some yellow tigers are much more pronounced than others, as is the green on the throat. Again notice the splattering of red going up the card, and the streak of "green", which is the lack of red, up on his throat just to the left of the adam's apple
