Perhaps a silly observation but on the Sovereign Mathewson (the PSA graded card), the alignment of the name on the bottom is a little bit off. If you focus on his bottom shirt button, you will see what I mean. Here is the Soverign followed by the Tolstoi card:

If you look at the Tolstoi Mathewson, the "W" and "S" more or less align with the bottom button (that is how it should be). But on the Sovereign Mathewson, the "S" aligns with the button. Not sure if it means anything...........all the Mathewson's that I see align just like the raw Tolstoi (consistently with the "W" and "S" under the button).
