This is a hand signed card, not a set insert.
It is signed in either Sharpie or Pen. The signature is solid and clean
This card is in NM condition. This is an estimated grade, use the scan as a better judge of condition.
The scan will show any imperfections, especially along the edges and corners. In the slab the card has a nice overall appearance.
This came from a large collection from a very reputable dealer. There is no 3rd party authentication. I suggest a PSA quick opinion for those unsure.
