Cool stuff. As I was reading, I was like "How is a Bobby Hull 1/1 auto not #1?", but hard to argue with the Tarasenko /3 on a already SP card, or the Gretzky /3. I might have ranked Pettersson lower, but in terms of current market value I can see how it gets there.
I also like the Espo Canvas, and anything from the 10/11 set with the classic 90/91 design.
