Matthew Douglas Halloran was drafted in the first round of 1996. He then played 6 seasons in the Padres and Texas organizations,but never made it to the majors. I got this through the mail several years ago using the one of the address list.
Johns Joseph Hamilton was the 8th pick in the first round of the 1991 draft. He made his major league debut in 1994 with the Padres, he pitched for 5 years in San Diego. He then pitched for three years each in Toronto and Cincinnati. He has never officially retired but hasn't signed a contract since 2005. Fleer Tradition was a good card to get signed because of the finish. I got it through eBay.
Charlton Atlee Hammaker played for four teams in his 12 year major league career, most of them with the Giants. He spent two years with the Padres. The card isn't really that off center, my scanner did that. I got this signed through the mail years ago.
