Something fishy about this 56 Mays

That can't possible be the card that was originally in that holder, can it?

Possible? Yes, it is posssible. Is your only worry about the centering top-to-bottom? The angle of photo makes it hard to gauge the centering, but it seems to be outside the PSA 7 guideline.
Photo angle make it hard to see frosting as well.

Two corners on the right look awfully shaky for a 7 too.

That is a 5 card in a 7 slab ....

I wish these sellers would realize they are turning off buyers and likely losing sales by using these cel phone photos that resemble the opening credits for Star Wars rather than a standard scan.

In order for that centering to qualify for an overall grade of 7, it would have to be 9OC. That card is not a 9 in any way. It looks like a 5 with poor eye appeal to me. Makes me think it's a phony slab.
