After reading this post, log onto eBay and type in "1968 Topps Harmon Killebrew." Buy it.
One in this condition should cost you about $2. One in much better condition about $5.
Take the card, admire it for a few days and then give it to a kid. It doesn't matter if it's a son or grandson, daugher or granddaughter, nephew or niece.
Explain that Harmon Killebrew was one heck of a ballplayer and one of the game's good guys.
Tell them of his 573 home runs, his 13 All-Star appearances and his 1969 MVP season.
Tell them about the time he hit a ball 520-feet in Minnesota or the time he hit a ball over the left field roof at Detroit's Tiger Stadium. Tell them how he was elected to the Hall of Fame in 1984.
And make sure to tell them about his character. That he was a nice guy. That he played fair and with humility.
