For such a limited card, I'm amazed at how many have been sold over the past few years. Is it the same one bouncing between different owners?
The card is described as high quality for the 100 extant, significantly better in fact than the average. Priced like an old master painting, the article mentions previous owners including WAYNE GRETZKY...
It does boggle the mind how money, stuff, availability, market and demand, continues to surprise and accelerate. American ephemera of high quality yields amazing prices.
