People love collecting T206s in a way that not everyone with a big bag of money can. The only impediment to building a set of 521 is cash, not availability. Collecting T206s in unique ways helps bring the collector closer to the set -- it becomes more personal. That is just one of the reasons why I love autographed T206 cards. And I am not alone...
