Posted two weeks ago about finding a set of 1963 Dodgers Pinups at a card show. Out of my price range for the set (including 3 graded posters), but I was intrigued.

Dug around on eBay and found a seller with a sealed envelope of the pinups, for WAY less than the opened/graded set cost.

So now I have this awesome full-set of pinups with a Koufax I’d really like to get graded.

So here’s the question- what’s the best way to prep a non-card for grading with PSA? I’ve only ever submitted cards and this 8x10 poster is bigger and more fragile than a card, especially with no top loader to ship it in.

I also have a hopefully Type 1 photo to send in, same concern.

Any advice?
