I got another card from the 1991 Orioles Crown set signed by sending another TTM request to Grant Jackson. He signs quickly, and I had a couple other cards that I hadn't yet gotten signed.
I found these two Topps cards (1973 and 1974) and sent them along to get signed. The last time I sent to him, I had gotten cards from 1972, 1976, 1981 and 1982 signed. He has a really nice signature, and all of the cards I have sent him look really nice.
I mailed to Jackson on April 27 and got the cards back on May 9, for a 12-day TAT.
