I didn't notice anything before I bid on the card.

When I opened it up the first thing I noticed was this strange spot.

It is in a few places on the card but the biggest and most noticeable one is under his foot in the black stripe area.

At first I thought no biggie just some Gunk on the Outside of the case.

But when I cleaned it it didn't go away and the case is smooth not scratched or anything.

It is hard to photograph.

It looks much much more noticeable in person.

If you tilt the card the right way you don't notice it at all.

But in most angles it is really noticeable.

The seller made no mention of this in the description.

It looks like moisture got in the case or something.

It looks like the Card in that small area is glued to the case or something.

I wanted to get peoples thoughts before I contact the seller.

I am thinking this happened in shipping.

Maybe the heat from outside caused it when it was in the mailbox?

I have never seen this before and have seen a lot of graded cards.

What should I do?
