The ultimate Michigan signed memorabilia piece?

Not at all an autograph hound, but I recently found a baseball I bought for my son back in 2004 when I found out that the Detroit Tigers Winter Caravan was going to make a stop at the Bobo Brazil Center in Benton Harbor. Though I gave it to my son back then so he could get it autographed by the Tigers players and staff in attendance, he's now no longer interested in baseball and told me I could keep it (as he told me, "finders, keepers). While it's likely that only die-hard Tigers fans would recognize the rather obscure members of the 2003 Tigers team who signed that baseball, one autograph in particular caught my eye when I found the ball buried in a box of belongings: that of then-manager and newly-elected Hall-of-Famer Alan Trammell. Bottom line: I have no intention to sell it, nor would I ever pursue buying anything someone else got signed by Tram. Why? Because somebody else's belongings don't mean nearly as much to me as this particular baseball---not only did Tram sign that baseball for my son, but he also took the time to interact with me and especially my then 9-year-old son, showing genuine interest in what my son had to say about his Little League team, even offering him advice on strengthening his throwing arm. Stuff like this, when attached to fond memories, mean much more to me than just some random autograph by someone famous.
