curved cards

[1970s]

Another newbie question:

My son and I just had fun opening a bunch of 1990 rack packs. A bunch of the cards have a uniform curvature. I'm attaching pictures, top and side views, of one card on a flat table.

Is this considered damage? Caused by some change in temperate during the 30+ years the cards were in the packs?

I assume the cards will gradually flatten, depending on how they're stored, but I don't know.

Thanks.

No that is not considered damage. They will gradually flatten out if you stack them or if you store them in a 9 card sleeve, top loader, etc.

Thank you.
