These odd angled cuts are a good place to start when detecting trimmed cards. You'll see it on many cards, although that Young is a little more on the extreme side it's perfectly fine. When you see a little bit of an odd angle just look at the other end to make sure that they are parallel, then by looking at the corners you can tell the other sides are good too. With that Young, you have a parallel top and bottom and perfectly worn and even corners, which is good. On some issues, funky cuts are more prevalent than others. Look at cards closely, especially from this era, and you'll realize it's more common than you think. A lot of times it's just minor though. Some people stay away from cards like that Young, but I think it's kind of neat because it tells a story of the process.

Here is a random example from Ebay that shows the same thing going on, albeit in a much more subtle manner. There is a downward, but parallel, slant from left to right on both top and bottom.
