Fairly recently graded by SGC.

SGC, who really knows vintage far better than any other grading company is totally correct about this card being 100% original and unaltered.  Unfortunately, it is a bit undersized.

For those who really know this issue, that shouldn't be any surprise. For whatever reason, Mathewson, and a few others from this set were almost always made short by Sporting Life.

I've added an image of a numerically graded example from PSA.

Please compare the size to my SGC card which is at least as large.

If you are more of a card collector than a label collector, this is a nice and affordable example of a very tough card.
