Simply a spectacular example of the rookie card of Hall of Fame slugger Harmon Killebrew, one of the key cards in the widely-collected 1955 Topps set.  A member of the 500-HR club when such a distinction had far more meaning than it does today, Killebrew was a four-sport athlete who signed with Washington and due to league rules, was required to stay with the Major League club for a minimum of two years despite being just 17 years old.  For five seasons, young Killebrew bided his time, finally cracking the starting lineup in 1959 and paying dividends for the Senators, as the slugger would club 42 home runs.  He remained with Washington and Minnesota for all but one year of his career, finishing up as a DH with the 1975 Royals.  His final stats include 574 lifetime home runs, a 1969 MVP award, 13 All-Star appearances, and a 1984 induction into the Hall of Fame.  

This card is virtually flawless, a brilliant yellow background contrasting with stark white borders and two clean, colorful images of "Killer."  Corners are razor sharp, the centering outstanding.  Seldom has PSA seen such a spectacular example; this is just one of 19 specimens to attain the MINT plateau with just one higher.  A truly wonderful, high-grade card, one of a trio of highly desirable rookie cards from the 1955 issue (the others, of course, being Roberto Clemente and Sandy Koufax).
