What kind of stain?

Can someone help me identify this type of stain? I hear a lot about wax stains & gum stains but this type of stain (found in lower left corner) shows up on a lot of my mid 80's football. It sort of reminds me of grease stains on a cardboard pizza box. Would this be some sort of oil stain? If so, how does PSA look at these types?
Thanks!

I've noticed this sort of stain on cards from just about all of Topps' 80s era issues. I remember opening up packs in the 80s and seeing stains like that on the cards, so it must be some sort of impurity in the cardboard pulp they used, or something that got on the cards during the printing process (e.g. a worker spraying WD40 on something while cards are going through the press).

I don't know. I never tried to submit a card with that sort of stain.

He said the lower left corner.

He said when
So you pulled it and that's how you came across the card. Makes sense.
