Here's a quick hockey one from Moser. The left edge has been definitely been trimmed, and perhaps all four edges. The corners have been sharpened too. The PSA 5 photo was blurry, so I had to keep the provided photos large to see the detail, but you can see the common paper fibers on the front and print marks on the back match up perfectly (see the green circles).
