My 45th Hall of Famer signed baseball was also my 28th TTM success - Andre Dawson. I mailed to Dawson on August 16 and got the ball back on August 25, making him a 9-day TAT. He charges a fee of $45 for a baseball, but looking at his signature, it is well worth it. He asks that people include an extra $10.00 for an inscription, but for me, I think the ball looks perfect as is.
Dawson was the 1977 NL Rookie of the Year and the 1987 NL MVP. He is a rare instance of a player winning the MVP on a last place club. Hitting 49 home runs that year definitely helped his cause.He was elected to the Hall of Fame in 2010 with 77.9% of the vote (his 9th ballot).
