The damage on the right side is almost like a notary's stamp was used on the card. There are several pin-like holes on it that line up in a straight line. Plus, someone with a red pen has made it a lot easier to remember that Ernie's lifetime batting average was .277 in 1969...no more painfully having to turn the card over to know that anymore.
And then there is the piece de resistance: the green star sticker that covers up some more red pen scribbles is a nice touch that pushes this damage from good to great!
