I remembered reading this some time ago but I assume Al was referring to the cards in this particular find and not all 52 Topps John Rutherford cards?
"[John] Rutherford (#320) is really the toughest card in the set," said Rosen. "Many of the Rutherford's have a paper wrinkle right through his forehead."
