Ok, Since most did not like my Billy Meredith 1013-14 Taddy & Co. pick, my next proposal would be the Ferenc Puskas 1947 Nannina. So let's start with the player.
For those that do not know Ferenc Puskas was a legendary Hungarian icon. He averaged nearly a goal per game at nearly every stop in his career - club or country. He is probably best known for his time at Real Madrid playing alongside Alfredo Di Stefano where they won many title (3 European Cups, 5 Spanish division)... and this is all in the back half of his career (after he was 30). Prior to his defection, he led Hungary to the gold medal in 1952 and the World Cup final in 1954 (where they lost 1-0 to Germany).
You can get some basic insights from:
https://en.wikipedia.org/wiki/Ferenc_Pusk%C3%A1s
In the end, he is rated as the #6 all time player by IFFHS, #7 by World Soccer, #7 by Top End Soccer and #17 by the FIFA internet poll. He was also given the IFFHS award for the Top Scorer of the 20th century and the annual FIFA Award for the most beautiful goal is called the FIFA Puskas Award.
Bottom line, this guy was legit.
So now onto the card. His rookie cards (as far as I can tell) hails from a 1946-47 Nannina issue from Italy. It includes many national teams and is made to be hand cut (think dotted lines like the Post cards from the 1970s).
Here are the current populations:
PSA has 3 grade d- a 2, 5 & a 6
SGC had 4 graded - an "A", SGC 45, SGC 50 and SGC 60
That is a total of 7 graded copies. It has also come to my attention that PSA is no longer taking submissions of this card, though I do not know why.
To follow up with a few of the points raised by others. This card does trade every now and then. The last time that it traded was on eBay about 6 months ago. A hacked copy brought more than $2k, which was quite surprising to me (I was not the bidder or the under bidder). Therefore, I can only believe that there are some people out there than feel that this is an iconic card. I surely do. With that, I hereby open the flood gates to other comments and points of view!
