For those who think these signatures look a little off, I believe they are ghost-signed—that is, someone other than Ryan Carter signed the cards.
Carter was drafted twice, initially out of high school in 1997, then in the 8th round out of the University of California, Los Angeles in 2000. He was taken in the same round as future pitching stars Dontrelle Willis and Brandon Webb, though such success was not in his professional future.
He played in the minor leagues from 2000 to 2003 and had modest success in the lower levels, striking out 132 in 138.2 innings in 2001. However, in his Double A debut in 2003, he went 2-7 with a 6.00 ERA in 17 starts in what would be his final season.
