16 years ago I did a couple of interviews with hobby legends Lionel Carter and Jeff Morey. You can listen to those on my website at:

I also visited the Leopold Morse Goulston collection of T206 cards at the New York Public Library and wrote an article about it (and even donated some missing T206 cards to that collection). Goulston had a gorgeous Wagner which is still in that library.
