“Individual” is the right word to describe him.  I remember in the 90’s, when I was in the memorabilia business, and ballplayers were selling their soles to show promoters, who sold player autographs for $25 and up.  Bob Feller refused to make deals with the promoters and would take his own table at memorabilia shows and sell his autograph to anyone who wanted it for $2.  I never knew if he was just cheap and didn’t want to give a cut to the show promoter, or if he just wanted to give the fans a better deal.  I got 3, one for each kid.
